No Power - ZR-1 Net Registry Forums

8upZR1 · 07-17-2007

I was wondering if anyone could help me out. I have a 90 ZR1. When I push the gas the car has no power. The car is running lean when I get on the throttle and the computer gives codes 21 and 33. TPS voltage high and MAP voltage high. The MAP sensor was replaced about a year ago. The TPS is original. If anyone has any info on this I would much appreciate the help. Thankyou.
