my check engine light comes on every now and then but when i give it more gas it goes away. can anyone give me any ideas.

chris it is extremely hard to say, the check engine light could be comming on for any of a number of things, it could also be a faulty light since its not staying on. i would reccomend that you check the diagnosis error codes from your car, it will narrow down the possibilites if there is something wrong.

the link for locating the box, and diagnosing the codes is here..http://www.myzero.com/electrical/code.html

or many other places on the club dsm page.

hope it helps!

maybe your MAF wire harness is lose and causeing your check engine light to come on as it loses contact with the sensor?

Why wonder... just ask the car. Everytime the light comes on it the ECU stores a code as to what the problem is. If you have a 1G look here to find out how to get the codes:

I have the same problem as you described. My check engine light comes on from time to time. It goes away if I floor the gas. I checked the code and it's #14 - TPS. You need to either replace it, or it might be possible it only needs an adjustment.

If the ECU is throwing error codes for the TPS, it's gradually gonna get worse until the car practically becomes undriveable above 3000 or so RPM.

It's not a cheap sensor either. I had mine replaced a few months ago.

I just bought one for the GTX, it was 246 bucks out the door.....

246 bucks?? damn, that's expensive...
Mike, didn't you use to make those engine error code readers? You were selling them for like 10 bucks right?

My car did that too a little while but it stopped now.. the check engine light kept going on for like 2 minutes then off.. until the car warmed up..
Now i have a really weird idle problem where the idle RISES, yes rises.. as the car gets warmer.. instead of drop as it gets warmer.. i never got to check the code, and when i finally did.. nothing..

Sup with that filter?? hehe anybody ever had this happen?

Sorry to cut you in the middle of a crucial discussion like an idiot

but what is that TPS (the holy piece of $246 value)???? :rolleyes:

Thanks!

TPS = Throttle Position Sensor. It's on the throttle body.

I had a bad tps for a year or so
it does just get gradually and gradually worse
look for them at a wrecker
I replace mine and got the isc and throttle body with it for 80$

Chris that is really anoying.

Not Chris' fault.
It was a test of a filter on the UBB

sorry guys....

the test failed :-(

you guys just happened to post while we were testing it (like 5 mins total)
DOH!

Well, its seems that I have a spare TPS now for a GTX if anyone is interested in purchasing it.

I put the new one on today and same trouble, intermitent #14 code from the ecu. Adjusted it and still same. Tried reseting the ecu, still same.....adjusted the throttle cable and bam, no codes anymore and my auto tranny shifts perfectly now......

Before anyone calls me an idiot, I'll tell you that I did try adjusting the cable before buying a new tps with no results in the positive direction.

So, the moral of the story, is check your throttle cable adjustment before you assume the TPS is bad.
