need help with my car

[ds52389]

Im a new member here but have looked on these forums for some time and i thought i would start by asking for help. I drive a 99 gsr, when i change into 2nd,3rd and 4th gear right when i let off the clutch and push in the gas nothing happens the car just starts to slow down. it feels like i let off the clutch and didnt push the gas but the car will eventually catch and go. One weird thing is that it only does this in cold weather. If anyone can help me with this problem i would be very thankful.

Also my car has t3/t4 turbo and has a aftermarket throttle body if that can make a difference.

it might be that ur clutch is slipping but i wouldnt understand y it would only do that when its cold

u running a stock clutch? do the rpms slam while the speedometer goes nowhere?

 

[hmongkie]

btw, whats ur setup? injectors? fuel management? etc?

 

[ds52389]

i have covered most the basics that i think it could be i cleaned the throttle body the clutch is almost new sage 2 and grips very nice but this problem never happens during summer only cold im just stumped.

the injectors r 440s sadly im runin a vtec controller saving for an ecu.

could be the tune then...

try changing ur tranny fluid?... im not sure how much an effect the cold would do on it, but its worth a shot...

It's probably your tune. It may just be misfiring and/or fouling spark plugs. Do you have a wideband o2?
