Leave the info here. It'* a good lesson.

That procedure and list of codes is not good for 94 or newer pontiacs.

It is ONLY good for 87-93.

I do not know where or who posted that... But lets set a few things straight...

On the GM cars, the last year for the Diagnostic Flash Feature was 1993 in all GM cars.... there were 94-95 models that still used the ALDL 12 pin connector and the 2 didget codes, but the Diagnostic pin was no longer present in the terminal and the PCM would not flash codes....

So for all informative purposes here, 1993 was the last model year for the Diagnostic Flash Feature...

The 1994-1995 Bonneville and other H bodies used the 16 Pin OBD2 connector and the 4 didget codes, but was still OBD1 compliant using OBD1 protocall, and you must have a scantool to read the codes on the 94-95 H Bodies...

As well a scantool is also required for all 94-95 Model GM cars using the 12 Pin ALDL

Well, it'* abvious that I posted it since it'* in this thread, so if it'* not valid for Bonneville'* then I'll just deleat it. If I caused any confusion or inconvenience, I appologise. Now let me place myself on probation and I won't bother you all for awhile.

I know you posted it... I'm saying I don't know where the info they got came from... we are always trying to get the truth out there... And I don't understand how you could pull codes on a 94-95 GM car when it does not have the Diagnostic pin...

Not Bashing you at all... we see a lot of that type of info out there and we are trying to keep everyone on a level playing field... You did nothing wrong, we just want to make sure that you and the other members will have the right info

Does that mean I don't have to put myself on probation.?

I appreciate the clarification jr's3800 , I was only posting what I received online. As you can see I already deleated the post and hopefully no one got confused.

This forum has helped me so much and I was just trying to help back.

Thanks again.

I changed the O2 sensor even before they checked the codes, but the codes showed throttle positioning sensor.
They haven't checked the abs yet.
As for the lashings, you're teasing her now Bill, she doesn't like to be teased. And let me tell you, she'* not gentle.

By the way, thanks for asking.

Have you repaired the TPS issue? This can cause a lot of driveability issues...

I'm locating one now, and will try to instal it either today or tomorrow. I didn't think it would make that much of a difference jr's3800, do you think it would? The only reason it'* being changed now is to clear the codes.

It depends on the problems you are having... The info from the TPS helps the PCM determine the Load( throttle angle ) and in turn helps the PCM determine fueling in conjunction with the O2 and MAF, Also this can afect the Transmission Load or upshift - Downshift...

Not sure that it will correct your issues.. But if you have or had codes for the TPS it may just help correct for a hiccup or 2
