My car is bouncing between rpms when i give it gas. I have changed the IACV EACV and ECU and went through about 10 harnesses. Im still throwing the P1508 after changing these units and I have now received a TPS code. I changed my throttle body for a new edlebrock 64mm with a new tps on it. That cleared it up but i still got this problem. I cant rev over like i think 4K and i cant drive it cause its too limp. I cant even reach vtec or nothing. Please help wit suggestions and flaming isnt necessary. GSR info is low at the moment so this is my last resort.. thanks

 

are you sure it's not your dizzy? crank sensor?
I don't have an obd2 car, but that sounds like what my DA did when the dizzy went out.
good luck

did u do a compression test?

 

make sure ur tps is adjusted correctly. .5volts closed, 4.5volts at full throttle.

 

The problem was a bad harness. I changed harnesses with a new one from honda and car functions perfectly. I swapped motors afterwards and the little hatchy pulling a 14.2 with a stock b16a2. thnks
