Misfire/hesitant acceleration etc etc!

Recommended Posts

Nope! :mad:

 

Fitted the new valve/hoses, and it's still the same :( Taking it to a VW specialist today, and if they can't sort it, I'll pay AmD a visit in a couple of weeks.

 

The car is soooo rough on start up, and really jerks when you take your foot off the gas in lower gears. Not great when you floor it either :cry:

Ok are you sure there is no codes that are showing after the vag-com test after having it tested??

 

:?

I Know a mobile Guy that sorted out mine.... if you can get to around the north London area or meet him some where i'm sure he can sort the problem out, let me know if you want his number if you want to go down this route !!

Cheers mate,

 

They use VAGcom at the garage I'm taking it to, so hopefully they'll be able to sort it.

 

I'll let you know.

keep us posted. sounds exactly like what i'm experiencing with my G60 right now.

 

i have done..

 

new oem plugs/wires and i cleaned the plugs again just about 50km ago when i did the o2 sensor.

 

new o2 sensor and all new wiring from the connector on. rigged up an a/f guage and seems to cycle fine and go rich on throttle.

 

new blue coolant temp sensor.

 

isv, carbon cannister and boost return deleted. ..performance seems to have dropped off when i deleted the isv/boost return which makes no sense to me. i might put them back on and see.

 

i also just had a new cat put on... i thought the proper backpressure would help... nope.

 

new oil and fuel filters.. oem of course.

 

only thoughts i have on it now are that its either a vacuum line leak... the line that goes off to the brake booster branches off a couple times which i dont like.

 

could be that i torqued the knock sensor down too tight and its picking up crazy knock from my old clicky motor all the time.

 

or.. timing is way retarded.

 

any other ideas?? serious loss of power.. and this comes after lots of work and LOTS of money and i'm p***** :x :x :x

If they can't sort it, I'm gonna be very worried indeed!

 

I'll let you know how I get on.

good luck andy.

 

i just had a chat with darren, and he suggested i check the 1 meter hose from intake manifold to ECU again since i've determined that the lambda sensor is good so its not that. i checked the hose a couple weeks ago and zip tied the ends to be sure it wouldnt come off under hard boost..but it turns out... the end that goes to the intake manifold has gone mushy! i guess when i was fumbing around back there running the air/fuel gauge lines i must have agrivated the old rubber. i cut off the end bit and went for a quick boot around the block and the power is back! thank god. to the parts store after work for a proper length of 1 meter vacuum line.

 

moral of the story.. just cuz you think its fixed/okay doesn't mean it is so check again... and daz is the man! woo darren saves the day again (and he's an ocean away!). http://www.g-werks.com :thumbleft:

Nice one, Guy :D

 

Had a look at the coilpack before, but not properly. I'll have a proper look this time.

 

Cheers.

Checked the coilpack, and didn't seem to be any sparking. Reckon it's probably a good idea to do the epoxy thing anyway just to make sure. Will clean out the ISV at the same time. Let you know how I get on!

Finally sorted today by AmD :D

 

Turns out the air mass meter was fitted incorrectly! Can't believe that 2 different garages didn't pick this up (especially the VW specialist :mad: ).

 

The car feels totally different and sooo much better. Idles nicely, has smooth pick up on acceleration and no jerking on decelleration.

 

Cheers AmD! :D

Andy,

 

You gonna be at the CCGB thing at Woburn Abbey at the end of August? Wanna see this VR of yours!! :)

 

Glad to see you got this waxed finally.. it sucks when even bloody VW can't diagnose the problem. Thank god for the specialists like AmD!!

Joe M, yeh, that's the thing. I've got a K & N induction kit (which was already fitted when I bought the car) and apparently it was the wrong way around! :shock: :roll:

 

Jim, yep, barring a disaster I'll be there. The car is running really nicely now, although still needs lowering, stainless exhaust, new clutch, front discs, resprayed bonnet (bloody stonechips :mad: ) etc etc...... :roll: Corrados eh?

 

Hopefully you'll be able to attend in something new too :) Any joy?
