fuel regulator ? and heat ?

[STRteg]

off the top of my head im not sure at the moment. the fuel pressure is running at max psi all the time.

Oh ok because I was wondering if the fpr could be bad,and thanks for explaining it to me

your car is running lean and is why you failed. w/ the fpr connected @ idle the vacuum pulls the fuel pressure down. @ atmospheric (line disconnected and wot) the fuel pressure is high. if it's a stock regulator then it's probably between 45-48psi @ atmospheric. if disconnecting caused the car to run better @ idle the fuel pressure is as if it's @ wot, but running the injectors per the fuel mapping. however, when you go up in load normally w/ the fpr regulator connected then your fuel pressure increases as well as increases in the map as well. if it's running great @ idle and low load w/ the vacuum line disconnected then it's more than likely running lean @ wot since the fuel pressure is staying at the same pressure and not rising like it should @ higher loads. your fuel pressure will be between 7-10 psi different between idle and wot.

if you have an adj fuel pressure regulator on it, get a fuel pressure gauge and check the pressure and get it set correctly...this is assuming you have a stock/non-chipped ecu. if your ecu is chipped then it sounds like it needs to be tuned.

It didnt fail it passed emissions great,it had failed previously because of a bad cat and in need of a tune up and its all stock just as tech 5 said,thank you for your input and knowledge

doesnt need to be tuned...

You have a stock car

plug it all back in and adjust the throttle screw on the tb not the one on the cable part, but the flat head right in the center above the air tube.... and you srew it out lefty loosie and your golden... also a good throttle clean would be nice while your there...

Thanks man I'm going to try it as soon as I get a chance i'll give it a good cleaning and adjust the screw,how much do you think I should adjust it? Till the idle is strong and healthy I guess?
