Did you still need help?
WHat size engine do you have?
dont know sorry
Do you know the code number in the computer?
Do you have a 4 cylinder engine?
Or a 6 cylinder engine?
Ok... I would check the fuel pressure regulator. It is located on the fuel rail. It is round, about a quarter size and has a vacuum line going to it. If the regulator is leaking gas than it can cause this problem. Pull off the vacuum line that goes to the regulator. Be absolutely sure there is no gas in the vaccum line. If there is, the diaphram has ruptured and there is gas entering the engine that is not accounted for and the regulator will need to be replaced!
ok ,,i will try it ,, i was actually thinking perhaps an air problem,,,or oxygen sensor..
I DO hope you found my Answer to be helpful regarding your vehicles condition. IF SO-please hit **ACCEPT** as you read this Answer, in order that I may receive credit for my time, thanks. BONUSES & Positive Feedback Most appreciated!
Please Note: I receive ZERO Credit until & unless you choose to ACCEPT my well thought-out Answer.
can i check it out first ?
Pull off the vacuum line and see if there is gas in it
IF so, the regulator is bad
if not ?
THen we move on to checking for air or vacuum leaks
You might have an air or a vacuum leak. This is very common! Open the hood and listen for a hissing sound when the engine is running. Unmetered air can enter the engine through a vacuum leak, a dirty airflow sensor that is not reading airflow accurately, an EGR valve is not closing and is leaking exhaust into the intake manifold, an EGR valve that is allowing too much flow.If it is hard to pinpoint take some brake cleaner or starting fluid around the intake manifold and vacuum lines and see if the engine stumbles or if the idle is affected. Be extremely careful when doing this!
Also, your throttle body may be carboned up and need to be cleaned! This can cause all sorts of idle and hesitation problems. This is caused by the throttle plate not seating properly. The First thing i would do is clean out the throttle body with some throttle plate and intake cleaner and a small brush. Another common cause would be the Idle Air Control motor. This is very common on older cars. The IAC motor gets lazy and cant keep up with the fast idle changes. Also when the IAC motor is out, I rec to check the passages for carbon build up. If they are plugged they need to be cleaned out.
Check for the following conditions:
Poor connection at PCM or IAC motor. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection. Damaged harness. Inspect the wiring harness for damage. Restricted air intake system. Check for a possible collapsed air intake duct, restricted air filter element, or foreign objects blocking the air intake system. Throttle body. Check for objects blocking the IAC passage or throttle bore, excessive deposits in the IAC passage and on the IAC pintle, and excessive deposits in the throttle bore and on the throttle plate. Check for a sticking throttle plate. Also inspect the IAC passage for deposits or objects which will not allow the IAC pintle to fully extend. Vacuum leak. Check for a condition that causes a vacuum leak, such as disconnected or damaged hoses, leaks at EGR valve and EGR pipe to intake manifold, leaks at throttle body, faulty or incorrectly installed PCV valve, leaks at intake manifold brake booster hose disconnected, oil filler cap, oil level indicator loose or missing, etc..
waiting for wife to get back. is that the most common problem ?
thank you,, i will be back later
YES... either the regulator is leaking...
Or you have an air or a vacuum leak
I hope this helps. You can always accept my answer now, and repost back again later on if you have any more questions. If you want to discuss it some more just hit "reply", it's free to do so otherwise don't forget to hit "accept" and leave positive feedback if you found my answer helpful.
im sorry it is a v6 3.2,,,does that change things ?
YES... those are lean codes!
CHances are you have a big fat vacuum leak!
Just open the hood and listen for a hissing sounds at idle or when the engine is running.
common areas that it could be? could it be a sensor? (oxygen, air flow sensor ?)
YES! Either an air or a vacuum leak or you have a bad mass air flow sensor.
i cleaned mass air flow sensor ,,but still diying out ,,,only runs erratic in drive and idle,,,,,park and nuetral its fine,,,, ?
sounds like by valve covers
