The other day when i left work the car hic uped for a fraction of a second when i took off and everything was fine..... Today while driving, the car shuttered and felt like it was going to shut off for about 10 seconds, then the check engine light came on and everything was fine after that, besides the check engine light being on........ Checked the codes gave me a 4-5 which i know means it's running rich.....What should i check for to find out what's the deal? Don't think it's leaking injectors, cause they're only 4 months old brand new. Any help ??

Check for liquid fuel coming from the evap canister.

When you say "evap" that's the same as the purge canister right? If that's what you mean , what, do iopen it up and look inside cause i don't see how to get it open...also i checked the fuel pressure while it was ideling , it is at 48 lbs.... i didn't set it , but isn't that to high ?

Yeah. You pull off the vacuum line going to it and check for gas.
Thats a little high but the ecm should be able to pull fuel out to compensate as its not extreamly high. YOu can try setting it back to around 40 and see if that helps any.

Okay now what?.....no fuel or anything is coming out the vacuum line and the purge canister doesn't seem to be saturated with fuel. Like i said the injectors are only like 4 months old and the fuel pressure regulator is a holley and that was put on w/ the injectors...TPS maybe?
