help, car going crazy

hey everyone,
So I just recently started having problems with my car and did some searching but I am still a little confused.

so i'll start at the beginning.....
I was cruising down the highway 60-65 in 6th and went to pass someone. And being in 6th gear the car kind of lagged to pick up speed, no biggie, then it started gaining, then it hesitated :confused: it only did it once so I didn't really think nothing of it. but when I got off the highway it kept doing it when I would start from a stop and row through the gears every time i reached 2K or so rpm in 1st, and 2nd, sometimes 3rd. so now i'm getting freaked out. When I romp on it though and really give it some gas it didn't do it.

So fast forward to the next day..
I'm cruising down the street and the car starts hesitating again around the same rpm, hmm. I get to a stop and the car starts losing oil pressure AND the rpms start falling :eek: starts sputtering like the motor is trying to stay on. So I decide to pull into wal mart real quick grab a quart of oil. I put it in and the low pressure and rpm falling goes away :) yay. So i come to a conclusion to change the oil and think it will help. nope :cry: . I start it up cold and I get the sputtering from the motor right away.

Everytime I am idling or going slow these symptoms will come up ( hesitation has gone away) can anyone help me out?? is it my oil pump?? I thought i'd be as detailed as possible to avoid confusion. please give any info you can thank you. :bow:

I drove it for lunch. the SES light came on. it's still trying to die on me. help me out guys

Your oil pump is not causing this problem. Your oil pressure is falling as a result of the motor. What is the code that is being shown from the light?

I don't know, I don't have any type of scanner or computer equipment for my car ( I need some for sure though). so the only way to tell whats wrong is to scan it?

Get to an Auto Zone, they will scan it and give you the codes for free. Usually a check engine light point right at the problem. Its not the only way, you could just start throwing parts at it :lol:

Of course you could just buy you a little scanner up there too, they have a small one I picked up for $50, good investment.

Yup, get the code(s) read and write them down and post - don't worry about the description.

lol I thought about throwing parts at it believe me. alright so i'll go to autozone and have them scan it for me, then post them up in here. thanks :)

on a side note. is a check engine light the same as SES light? I don't believe i've seen the check engine light light up in my car before. hmmm. thanks again though i'll post up the codes tomorrow.

Yes, the SES and the check engine light means the same thing - we have the SES.

Yep, just get us some codes and we'll help ya get it runnin right again.

k went to autozone....so here goes

P0102

P0122

P0171

P0174

I thought I was only going to have one code lol. I know one of them said something about the MAF but don't remember. thnx for everyones help :)

:eek:

OK, so u have:
0102. MAF circuit low input
0122. TPS sensor low voltage
0171. Bank 1 too lean
0174. Bank 2 too lean

Start with 0102, check the engine sensor fuse in the fuse block under the hood. See if its blown, pretty common, could make them all go away. Of course check all the connections at the MAF and TPS.

k, I will check all those out. I don't have the car with me ( i didn't want to make it worse so didn't drive it today) so I will post up what happens as soon as I can.

If the fuses are good, check to see if the MAF has any oil in it. That will kill it.

k I checked everything out, and everything was connectect etc. but my car is still throwing the SES. what could it be?

^what and where do u put the oil in the MAF

:lol:

You don't put oil in the MAF.

What he was saying was to check to make sure the MAF isn't oily from excessive air filter lube or dirty. Get some electrical connector cleaner and spray the MAF if it's dirty.

lol I figured I didnt have to put any oil in there but then he said that ( i guess i read it wrong) and got confused cuz i've never seen or heard of putting oil in it lol. but ya i get it now. i'll go buy some MAF cleaner and clean the SOB. thnx. :)

ok so i cleaned the MAF with the proper cleaner (almost used the whole can) and cleaned the connections really good, but I still have the SES light. I'm guessing it's because bank 1 and 2 are still lean?? IDK this car is stressing me out. any more ideas I could try?? i'm really trying to avoid taking it somewhere

But is the car still acting bad? Even if it resolved the code, the light will stay on for a while.

The only time Ive dealt with this problem and it wasnt a dirty MAF sensor, it was the injectors. Swapped them out with some used ones and it cleared right up.

Reset your computer and wait to see if it comes up with an SES light again.

well i took it for a little drive after I did all that and it ran fine, just the SES light was on...I also thought one of the probs might be the injectors because of the two codes saying bank 1 and 2 were lean,hmm.... but how do i reset my comp? disconnect the battery? thanks for everyones help

To reset the computer
1) Turn the key on but do not start car
2) Pull the PCM Batt and PCM IGN fuses in the engine compartment
3) Wait 5 or so minutes
4) Turn Ign off
5) Replace fuses.
6) Start and drive car.

ahh.. I'm going to have to write that down..

UPDATE- I took out the car and drove it for about 20 min (longer than last time) and the SES light went off !!!! thank you everyone for helping me out. I'm hoping the light stays off lol thanks again I appreciate it a lot. :)
