Ever since I bought my car, it will not idle for about 30 sec. after I put gas in it. I have to feather the gas to keep it running for about 30 sec. and then it runs fine. Is this a common problem on boosted GSR's? I am unsure what EMS my car has in it and relize this is probably required information to solve the problem. Any have any ideas? Thanks

 

umm...that is not common. check your fuel pressure when you first start it. definitely find out what your car has.

 

obd2? if so this is common

 

I am running an OBD 1 ECU.

 

okay lets have a full listing of your equipment otherwise it's impossible to diagnose.

I would imagine your car is OBD2 but you are running a p28 or something of the like. Correct?

 

obd2 cars have this problem a lot when running the obd1 conversion, i honestly forgot what the issue was tho

 

By the way, My car is a 2001 GSR with stock head and bottom end.
I bought my car with everything already done but I will tell you what I can. The ECU in my car is larger than the original one that is sitting in my garage. it has writing on it that looks like it is from a wrecking yard that says "95 GSR". The factory numbers on the ECU are (37820-P72-A01) & (813115757) My setup is as follows. My call also has an Intermittent erratic idle that jumps between 900 and 1500 RPMs.

Drag 3 Turbo Kit @ 6PSI
550 RC injectors
FPR and gauge
Walbro 255 Fuel Pump
70MM Throtle Body
Skunk 2 cat-back exhaust with Cat

 

do you know who tuned the car? what engine management system it's running? any more info? do you know who did the install? could be several things but I'd say more than likely it's a tuning issue.....

 

The guy I bought the car from said he worked at Speed Shop in Tacoma Washington and he tuned it him self. I emailed him to see if he can tell me any details. Thanks for your replies.

 

i have an 01 gsr with a greddy kit, same damn problem. whats wrong with feathering it immediately after?
