prime the fuel pump by turning the key to ON, without starting it. it should be a smooth, quiet hum. im betting its the cat clogged up, or fouled plugs. fouled plugs tend to keep a motor running until its under load. take your ICM to autozone and have them test it. then have them check your coil packs with an ohm meter.
is it throwing any codes? and when pumps go bad, they usually give you bad trouble starting.

ok finally got it home and have codes of P0171 and P0403. it starts up fine and idles then it sometime dies havent drove it that far really since i dont want to take a chance

System too lean on one of your banks.... Could be a bad O2 sensor, vacuum leak around the manifold, etc. If it said both banks, could be vacuum leak anywhere, dirty MAF, clogged fuel filter, bad fuel pump, etc. You also have an egr code, and you usually dont get any driveability issues, but I have seen where they are stuck open, and they'll kill the engine.

try pcv valve. my gp threw system too lean bank 1, and i swapped out my pcv valve ($2 at autozone) and it hasnt thrown that code since.

^^Then you got lucky because too lean bank one means a vacuum leak so QUIT GIVING BAD INFORMATION. I WORK FOR AUTOZONE AT NIGHT AND YOUR THE KIND OF PEOPLE THAT MAKE US LOOK STUPID.
Don't worry...I'll find you in the system and start calling your store and having fun with that. Ever found a radiator for a 1970 Beetle? Or a set of brake pads for a 1983 Corvette? Let me know when you get them and find me.
Anywho to azlegalthief:
Bank 1 System too lean is a vacuum leak like I had already stated. You should check all the rubber fittings around the plastic vac. lines that run from your throttle body around to the fuel rail, under the supercharger snout to the lower intake manifold, then back around the back to the MAP sensor...there is also another set that runs from the throttle body to the EVAP canister on the back of the supercharger.
Only reason I don't think it could be a vacuum leak there is because of your second code being for the EGR Valve. There are 2 thin gold colored pipes running to the intake manifold and then to the rear exhaust manifold. If the one on the intake manifold side is busted...that could be giving you some issues as well.

your assuming that the too lean code is directly related to the issue...... so how many times have you had a problem, and a code that wasnt related? im guessing more than once.
05-01-2011
So, your saying a PCM is going to throw a code when the issue doesn't exist?Originally Posted by L36pro
Your logic = flawed.
BANK ONE LEAN = VACUUM LEAK. Look it up child.
05-01-2011
im not saying when the issue doesnt exist. use the reading mod. im saying that a code has been thrown to an issue that is completely unrelated to the problem that you often notice. so in this case the lean code could be something completely unrelated to the problem he is noticing..... reading mod.
05-01-2011
Oh really?
What else does a vacuum leak pertain to when you have a vacuum leak?
05-01-2011
the code doesnt say vacuum leak in your engine. it says system lean, which can be thrown by ANY NUMBER OF THINGS.
05-01-2011
BANK ONE LEAN MEANS VACUUM LEAK.
Maybe try researching or check your awesome autozone scanners when you get into work.

Lean bank is 99 percent of the time a vac leak.

and bank 1 lean is what my car was throwing when my pcv valve was locked up. its basic maintenance anyways. are you gonna hate yourself for shelling out 2 bucks on a pcv valve that hasnt been replaced since your last UIM job?
05-01-2011
A non functioning PCV valve can cause a vac leak itself

05-01-2011
exactly.
05-01-2011
well i thank you for all the advice here and will check in the morning for some of the issue with the vacuum leak. i thought it might be around the intake but will have to see if i can find a way to check that. but first things first, check vacuum lines, check pcv valve, three clean egr and check tubes... once again thanks
05-01-2011
starter fluid for checking for leaks.
05-01-2011
carb cleaner or throttle body cleaner and or ALOT of soap to little water and that way its really bubble's alot so you can see for leaks.
05-02-2011
yeah, that what i was think. small propane bottle with no flame also but carb cleaner or starting fluid... thanks again
