g60 Surging in first gear

[RoccoG60 0]

hey all, im new to the forum and new to owning a corrado. I absolutely love the car but just having a few problems. I mainly drive like a grandma but on occaision when i need to accelerate quickly for an on ramp or from a stop the car seems to surge in first gear. Feels like it get surges of power then goes away as if the charger was unhooked. As soon as i shift into second it pulls hard. rarely it will surge once or twice more but definetly not in third fourth or fifth. The only other info i have is that sometimes i can hear the charger whine and sometimes i cant. If i 3/4 throttle it in first it wont buck but at WOT it does. Looking for :help: I love this car and just want it to run correctly. As far as any mods, its stock to my knowledge. Thanks in advance!

belt slip?

Loaded question mate,

It could be fuel pressure that's low,(old partially blocked fuel filter),rotted/old vacuum pipes,FPR pipe that's split,bad/old plugs,ign. wires that are past their best,hall sensor inside dist. playing up or broken loose connection(common),tired fuel pump,CO pot that needs adjusting,blue water temp. sensor playing up etc,etc.

Try the simple cheap things first.

Yeh, i'd go with belt slip. Drive down a road with houses or thick hedges on both sides that are very close to the road, open the windows and see if you can hear it slipping if you boot it. Also measure the diameter of the charger pulley - see if it's standard or not.

i dont hear any belt slip. Its got new plugs in it, NGK platinums with the 2mm tip or something. Old plugs looked white when i pulled them. the new ones didnt seem to make any difference. As far as testing any of the sensors how can i go about it? This is my first corrado, havent even had it for a month. As far as boost, its running 10psi on a gauge, the rubber intercooler hoses have small cracks from being old that leak slowly when i did a pressure test on the whole system. I dont think those pipes are in nearly bad enough shape to cause this. It idles smooth, no vibration. ANy how to on testing the sensors? any help is appreciated. going to check the pulley size in a few minutes. thanks!

One thing I would recommend - if you are within reasonable driving distance of G-Werks (in Littlehampton) get yourself down there. A few mins with Darren will save you chaning things you don't need to....

Unfortunately in im Florida about 30 miles north of Tampa in Spring Hill. Any recommendations for a place near me?

 

Any other recommendations for what i can do/test? Thanks!

Again....can anyone give any more info on this? The car has a set of Bosch wires on it that look relatively new. the contacts inside have no rust or oxidation. And there dont seem to be any pinches or kinks any place in the wires. The digital temp readout in the dash works from what i can see. Does the blue sensor have anything to do with that or would the readout work even if the sensor wasnt functioning properly? I dont see or hear any vac leaks and believe they are all routed correctly :confused4: . Please dont let my post die. :help: Im just asking for a little help :help: . I have money, but not enough to start with no clear direction and replace random things. :shaking: Thanks again

OK, probably not the easiest thing to visit G-Werks then.... But even so I would recommend you call Darren there (+44 1903 730006) take him through the issue and get his opinion. He's very, very good at diagnosing G60 problems :notworthy: and should be able to give you a starting point for what to try.
