After running the car for a while i tried unplugging the mass air meter and the car did not start when it was unplugged, i then plugged it back in and it started, today though i went to start the car up this morning and it started right up i did not have to crank it at all, though it still died as soon as i hit the gas, it seemed to run a lot quicker today also, its weird sometimes it starts right up or it does what i have been talking about

Default update!! still need help!!

So I finally got the starting problem figured out, it was a clogged vacuum line under the manifold, but the car still dies if I hit the gas right after start up, and it still has poor acceleration, and sometimes when I start the car the rpm's will go up to around 1500 and the car will drive like a rocket but then when I come to the first stop sign and the rpm's drop down it immediately stalls right away, its like it gets a burst of energy on start up sometimes, but any other time its just really lacking power and acceleration and it also gets terrible gas mileage, since i got rid of the starting that eliminates a lot of things so maybe you guys can shed some more knowledge on the situation, thanks

my car had a similar not sayin the same but similar problem when the catalytic converter took a dump, it would stall when hit the gas but not right away, it also stalled when i stopped, wouldnt pass 15mph and sometimes it drove like a champ but yeah i changed the cat and been driving the car for the past year and half. not saying this could be your problem certainly dont want you dropping parts on the car but just posting my experience

Yea I have taken into consideration that it may be that or that its clogged, were their any other symptoms, cause mine goes more than 15mph and did it only stall right after you started it for a little? Thanks for the help this whole thing has been a real PITA cause i have been trying to figure it out for months and none of the local mechanics have a clue

well the car wouldnt stall when i started but wouldnt accelerate only able to rev it while park, if i put it in gear and giive it gas it would stall right away, then one day theres a little plastic tube after the exhaust manifold that lead to the secondary air pump about 2"" long, it popped and the car ran perfect, no exhaust tho sounded like it was all headers and every time i would replace the plastic tube the car would stall but then blow it, point is that i traced my problems to a bad cat

So you disconnected this 2" pipe and I'm guessing it was then running without the cat and exhaust, and it ran fine then, could you send me a diagram or part number of this pipe so that I could try it, thanks

Have you replaced all of the vacuum lines? The crankcase valve?

Gotten a chance to run codes?


That tube that trixzta is talking about is not on your car. That started in 1997. Pull the front 02 sensor and see if that helps. That will reduce the backpressure. You could also have a shop check the backpressure.

I just had all my vacuum lines cleaned out, they were all fine but their was just a clog in one of them and once I cleaned it the starting problem was resolved but I still have the power problem, and i have not gotten that valve yet because i am going to run seafoam through my brake booster line and see if it does anything, cause maybe its just clogged, but if not im going after that valve, could it be the TB maybe??
And i will pull the front one and see if that does anything and ill have the backpressure checked, maybe its the o2 sensors themselves??

Did you test it the way I mentioned? Pull the oil cap and see if air is sucked. The valve is overlooked, usually original and it causes a lot of problems.

Yea I pulled the dip stick and it started to stall and shake really bad then I put it back in and it didn't want to stall anymore, I'm guessing that means its most likely the valve then right?
