potatonet

about 3 weeks old, so its not that.

I am thinking grounding wire perhaps

brand new

ok sounds good will try this, there must be another sensor failed elsewhere I cant think of any besides black water sensor, what sensors could fail and where are they? I have replaced oil pressure and temp along with blue water, thermo, and aux fan.

ok, so again, I have been having problems with my corrado and I have replaced alternator, tried a different dizzy, blue temp sensor, and havent been able to find what the problem with my car is. I got the system to go above 500 RPMS to about 800-900 where it should idle, I rev it for a few seconds and then the thing just pops back down to 500 rpms, when I rev it there it doesnt rev, all the excess gas goes out the tailpipe. it will intermittenly jump revs up and down very quickly too. it sounds like I have something hitting a piece of something randomly as well, cant figure that one out, timing is dead on if you were gonna ask. sometimes when I try to rev it it will only allow me to hit a max RPM like 3000 for instance, and sometimes when I turn it over it just doesnt have any problems, all of these tries are within 15 mins of each other, I have a multimeter and tested ISV, back of throttle, blue temp, everything. I have fuel and spark it just the computer is limiting it by something, dunno what

ok its not the blue temp sender its something else, sensor reads fine. the car idled correctly for about 10 seconds after I altered the vacuum pumps hose config, I revved it and it dropped back down to crappyness, it just sits low, I have fuel flowing out because the spark plugs are black and the excess is coming out exhaust, computer is being retarded and getting snagged on something that is making ignition idle at 500, I am about to take it to a shop, 3 hours of testing till I do, If anyone just randomly knows what it is CALL ME. I need this thing to work today. 1-707-477-4203

ok been having problems getting my car past 500 RPMS a lot lately, dont know what it is, though it was a vacuum leak. well before I work on it tomorrow I thought tonight I would check to see if I could hear anything first, I start the car and it sits at 500 again, I unplug the blue temp sender and it makes no difference, I just replaced the sensor 3 days ago and it made a slight difference then, it allowed my revs to go up for once, wondering if there is faulty wiring somewhere cause I dont know where it is.

you might want to chekck your vacuum lines, my car rose up in RPMS when I shifted and I had a vacuum leak, yours is down so I dunno. sometimes my car would increase in RPM's till redline then I would tap the gas and it would go away. check your lines thats all I got to say. my car doesnt run right now and I am replacing check valves and line this weekend.

ok this I know I have a 1 meter hose that I cut to size and it works fine I am just looking to see if anyone has a list of the sizes of hoses and lengths of them, thanks

I need a list of the vacuum lines for the PG g60 engine so that I can get them ordered or sized at a shop. thanks guys.

mine tweeks out once in a blue moon, maybe this was one of those times.

improve matters would be to replace vacuum system, oh wait thats happening tomorrow, YAY!

Time to REMAP once again, great, maybe I wil just buy a chip anyone got any suggestions?

this car is sooooo jacked up. I replaced the vacuum hose to the ECU, 1 meter right..?, and the car now idles much lower like 750 range, there is definitely a vacuum leak in there cause you can hear it when you attempt to rev the engine. the only thing that bothered me was the fact that the old hose was 85mm instead of 100mm. will change all vacuum hoses this weekend and will post results then. thanks guys.

interesting

you are a genius anyone want to go in together with me for 30# injectors, 110 dollars?

ok I replaced the blue sender, did fine for a minute or two, then haltered to a stop, makes me think vacuum hose, what I dont get is why it sounds like it is pinking on some cylinders going to go out and buy a sensor to test fuel lines and a multimeter for spark yadda yadda, it just sounds like knocking I hope its not a rod.

021906031 is the part number I came up with, are these actually 30# injectors and can I use them on my G60, or do I have to buy racing injectors?

ok so I plugged my 200 amp starter charger in and it blew the fuse for my garage, should have turned the lights off. anyway I started the car and then proceeded to pull the blue temp sender line off, when I did, nothing happened, revs didnt drop or rise. unplug the vacuum hose from the throttle body and the revs rose to about 1000 rpms, it was the best moment of my life, plug it back in revs stay there till I touch the throttle, they slowly climbed like they did when I drove it the last day it worked, then they kinda just died down back to the 500 rpms which it idled at before, so tomorrow I am going to the local place to pick up about 4 of those blue senders being that I replaced this one a year ago, cant remember if it was the original one or not, anyway faulty new one, stupid afterarket VW parts. will post reply with tomorrow's outcome. cheers. BTW Insane_VR6 I have the corrado club of canadas calendar tell AHN that the headlights look awesome and nice job on those Red LCDs.

nevermind Insane_VR6 I appreciate the information, keep typing them that way, just frustrated

sounds good, sorry supercharged

so after reading another essay by insane_VR6 I still dont know what to do, should I go buy a multimeter and test the stuff? Why does it idle at 500 and why does it not make a difference if I hit the gas or not? I just replaced the ignition switch, the thing is that the problem progressed to a worsening effect. is it a vaccum leak, does anyone have anything solid to say before I go out and buy all of these metering tools and fuel pressure gauges and VAG-COM cables and programs and bleh. I got the throttle body to ECU thing and the blue temp sender and am gonna check those tonight. will report more later. keep thinking guys, and Insane_VR6, try to keep it to a few sentences and not an essay, and where do I get a multimeter and how much being that I am US?

yeah noticed that one first topic of mistralls

right but why would it blink when the temp goes up, I have plenty of coolant and the tank is 3 months old.

ok so we all know potatonets corrado is in the crapper once again. lets start out with this: Drive the car around all the time, every once in a while for about 30 seconds I will lose HP severely, dunno what it is. about 2 weeks ago my car started driving around with no HP, couldnt get the revs up very high very quickly at all. got it home that day and it was fine. next day I start it up and it idles at the first mark after 0 RPMS which I am assuming is 500 RPMs. thought it was alternator didnt know really. since then it has been sitting in my garage being worked on by me. Things I have replaced recently(last month and a half): fuel filter timing belt alternator water pump radiator O2 sensor everything else in coolant system fuel injector seals crank bolt top radiator hose oil pressure senders oil hoses to charger oil cooler (front mount) EVERY FREAKING THING!!!!!!!! suspicions: fuel pressure regulator ECU (rebuilt a year ago) ...thats all I got the car idles at 500 rpms once again, checked spark in Dizzy = perfect, check fuel pump flow = perfectly fast, timing is DEAD on I checked 3 times. If I floor it nothing happens, if I unplug the blue temp sender it doesnt start so I think that works. all belts are tight. compression test came back 110 - 130 across the board so I dont have a sucked valve. Charger works fine. Something is not right. I dont know what it is, all I know is that I couldnt get the revs to move for the life of me, changed the Dizzy to one from a fox (should idle at about 3000) =-), didnt do crap, =-(. I really dont know what is going on here guys, I cant get my car to move an inch and I need this thing. experts please help I know you may be repeating yourselves but its for a good cause, engineering degree. thanks guys. I need everyones help on this one.
