Well that kinda suck lol if there is a leak. It happen after replacing throttle body. The throttle body came with another tps and ISC which i used. The other thing i did was run the VAC lines for the EGR. Its not hooked up to the solenoid yet though. Acceleration fine its just if i try to hold the rpm steady say like in idle it kinda drop a few hundred then goes back up.

 

Dude, you need your EGR valve hooked up...I think that's why your rpm's are searching...

 

98MITsGSX you 100 percent sure.. because if soo ill hook it up. The car didn't do this before and it was all disconnected. Also there are ppl who disconnect there egr and evap system and haven't complained about this over at dsmtuner. But if your 100 percent sure ill go buy some more vac hoses and try it out.

 

If a car has EGR, it has it for a purpose....you need that to run properly...I am sure, I even talked to my father about it...he said the same thing. You need EGR to keep backpressure regulated...blah, blah, blah. He said hook it back up and you'll like the result...I dunno, I usually listen to my old man.
