Running awfully rich???

shurb125 · August 22nd, 2008, 05:30 PM

When I start my car weather it's hot or cold and it runs for just a minute all you can smell is gas fumes enough to burn your eyes after a while and this is with the garage open and airflow. I wonder if the fuel pressure is to high, the shop I had it dynoed at set it between 38 and 40 psi does that sound high? Does anyone have any suggestions or advise? Thanks agin for your help!

Slight hesitation between 1K and 2K but after that she runs like a champ. But the exhaust fumes are what kills me!

No MIL light

i take it the fumes dont bother you once youre moving. sounds like you are dumping too much fuel at idle. fuel pump whining at all? MAF calibrated correctly?

93hatch · August 28th, 2008, 02:40 AM

is ur exhaust dumped and do you have cats?

JBIGBOOTSY · August 28th, 2008, 05:57 AM

It will run rich till you hit 182* if it's anEFI car.

MAF is calibrated for the 24# injectors that i have. No whining of the fuel pump.

It is an EFI car, but it seems to do it even after it passes 182*

I'll pay more attention the next time I get it up to temperature and I'll let you guys know. Thanks for all of your help.

do you still have the fuel vapor canister still on your pony???
I removed it because its a waste of space and serves no purpose. So i tend to get a gas fume smell during start up, onces she heats up it desacrates.
