Im running out of ideas here ive replaced the MAF and all the filters and such new plugs and wires, it still runs crappy at idel and gets poor mileage + it runs rich....what i need if possible is DETAILED instructions on how to check the TPS ,,sorry im not good and electronic stuff hehe...thanks

This link may help you out some

Matt, go to Techinfo and use the flash feature to check for faults.

Next, go buy Chilton'* #28200 manual. You need it for the power steering pump change anyway.

If you get in a bind, I can get you the info, but you really need this book.

BTW, the #1 reason for running rich is typically the O2 sensor. How many miles since it'* been changed?

2000 miles its a new NGK 02 sensor..35 bucks..

NGK makes a o2 sensor? Besides the point, I (and many others) ONLY recommend the AC Delco replacement.

I doubt that the TPS would cause the symptoms that you've reported, but if there are TPS error codes stored then it could be defective. On my '92 and '93, the SES light will turn on if the TPS voltage is too low or too high, and it will store an error code.

First, though, are there any SES error codes stored, and is the SES light on?
Has your catalytic converter ever been replaced? If it'* plugged, it can cause a rough idle and poor fuel economy. The EGR valve can cause a rough idle too, and so can many other things.

You can check the TPS yourself using a multimeter. First you can check the voltage at idle. I don't remember which 2 of the 3 pins to measure for this, but if the DC voltage is not in the nominal specified range and your TPS has the 2 ovular mounting holes, you can loosen the mounting screws a little and adjust the voltage to within the nominal range. It doesn't take much, and the range is in millivolts so it'* kind of narrow. If the TPS has 2 round mounting holes, then it'* not adjustable. Then shut off the ignition (key off) and remove the electrical connector and use the multimeter to measure the resistance as you move the throttle arm by hand. The resistance should vary smoothly as you move the throttle, without big leaps in resistance or spots that read overrange (open circuit) or high resistance measurements.

By the way, my'93 SSEi was getting terrible fuel economy even though it ran great at the time. I replaced the o2 sensor with a Bosch unit and got better MPG but only for a month or so. Then I replaced that Bosch sensor with a Delco sensor and it'* been getting better MPG for several months since that.

NGK is a branch of Ac Delco, isnt it? If they do make an O2 sensor then Im gonna try it out.
