What's up guys I have a 92 trans am with a 350 tpi. I decided to take the accel runners I had off and go back to stock. Car was running excellent I got everything put back together and it started to run horriable. I checked the codes and I get 22 33 and 34. The tps is new I've never had problems with it. And the map wad working fine before I tore it apart to get the runners off. I checked for vacum leaks and can't seem to find any. Anybody have any other suggestions.? Thank you

 

Vacuum leak shouldn't cause those three codes I wouldn't think. Pinched wires, bad/loose connector? I'd start ohm testing circuits and such.

Awesome I'll start to check all the wiring tomorrow. Maybe I pinched a wire somewhere or something.

 

Also does anybody know where the map sensor vacum line goes too? I have it to the egr.?

 

MAP sensor can go to any constant vacuum source.

 

Ok so the egr should be good connected to the map?

 

NO. The egr should be connected to the egr solenoid which should have vacuum sourced from the port under the TB. The MAP should be connected to a manifold vacuum source, the plenum should have a port right under the MAP specifically for the MAP. https://www.thirdgen.org/forums/tech...iagrams-i.html

 

So went outside and switched the vacum from the egr to the port to the plenum side and it seemed to work and I accidently pinched the blue wire to the tps when I was taking the runners out. Everything is back to normal no more codes thanks for all the help.
