Codes 33,34.....should I look at the TPS?
 

I have gotten both of those codes, and I am not sure where to look. I recently replaced the maf, and it is not the wire filament type, so I don't believe that is the problem. I have read the archives on the subject, and many people seem to point the finger at the tps, could this be the problem?

I can get it to idle most of the time, and it will idle just fine, then as soon as I press the gas pedal the least little bit, it immediately dies. I did replace the tps plug (not the sensor) last night and that seems to have helped it a bit. At least it is idling now, and that another reason I thought it might be the tps. Ideas? Thanks

Have you replaced the maf relays? power and burnoff?

No, I have not. I don't know how to check any of those, nor do I know where to locate them. Any help with that would be great. Thanks

I have an 88 IROCZ. The relays are located on the firewall, driver side. There are 3.
Looking at it from the front of the car:

1. The MAF relay is on the far right.
2. The identical relay immediately to it's left is the fuel pump relay.
3. The relay on the far left is the MAF burnoff relay. It looks different than the other two.

When you pull the connectors check them carefully. My MAF burnoff relay was a mess of gook. A good parts store will be able to give you a new relay and order you the proper pigtail. Good luck.
