I haven't tried that. How do you do it? is there a post for it?
Also, JWIKOFF99 suggested swapping the map sensors and disconnecting the battery. Again, I don't know how. Post?

Thanks.

I mant I haven't tried resetting the ECM etc.
And I don't know where the MAF senseors are either that'* why I'm asking if there'* a post already there.
Thanks

You can't swap the ECMs between those two cars. You can reset the ECM by disconnecting the negative portion of the battery, then turn the key to discharge any residual charge left in the electrical system. The MAF sensor is the black rectangle on the throttle body that will be facing you. Held in by three screws. It has a wiring connector with three wires.

Ok. Thanks! I'll reset the ECM and see what gives. Here'* one thought... When I got it it had regular unleaded gas in it it ran out while I was fixing it. Then I filled it up with premium 91 octane and put a bottle of injector cleaner. I did not reset the ECM. Could it be thinking it has lowe octane gas and therefore changing my timing, etc? Causing it to overheat and guzzle gas?

Ok. I disconnected the battery, then turned the ignition on and left it for about 10 min. Reconnected. No discernible change.
Car is starting to have first time no start problems. I can avoid it by pressing the gas a little.

Hello!

I'm sorry it took so long to get back to you. I've been buried in work.
Do you have a diagram for the engine, pointing out the location for the sensors, the fuel pressure regulator, etc.? I want to replace the FPR but can't find it
Also, I read a post in techinfo about adjusting the TPS. I might just do that and clean the TB at the same time.
I'll let you know what the outcome is.
Thanks in advance for your patience and help.
Ah! By the way, I tested my exhaust system with a laser temp probe and found a 300 degree difference between the cat and the pipe after it. That means that my cat is plugged and therefore heat cannot escape. That accounts for the overheating issue. Over here, I can have the cat removed and that will be the end of that. Should I reset the computer after that?

It'll take me a little while to dig the sensor diagram out of my service manual and scan it.

As far as the cat, my suggestion is a high flow 2.5" universal cat from Magnaflow. That'* what I've got, changed the exhaust tone for the better, obviously cleared up the clogged cat issue I had, and leaves just enough back pressure so I didn't lose low end torque. Then reset the computer for good measure.

Think I'll loose too much low end torque if I leave a straight pipe to the muffler?
I appreciatte the scans, Thanks

Silly question, maybe...

I disconnected the negative side from the battery , turned the key on the ignition and let it sit for 10 min. Does that clear the ECM and the ECU and PCM? or only the ECM?

The ECU, ECM, and PCM are all the same thing, the car'* engine and transmission computer. Your procecdure for resetting it is correct. I'll get those scans to you tomorrow.
