Is someting wrong with my Z? - ZR-1 Net Registry Forums

ffvetteman · 06-24-2006

The past 2 times I have taken my ZR-1 out it seems to not have the same power it used to. It almost seems at high RPMs under full throttle, its not pulling. Kinda feels like it has got a small chug in the 5K -7k RPM range.
The car is a stock 92 , only mod is a Doug Rippie chip and it has 38K miles.

Im not sure if something is wrong or not, because sometimes it feels just fine, but other times it almost feels like it is chugging. As far as I know the plugs are stock and the wires are for sure stock.

I was going to start with changing the plugs and wanted to check what are the best stock plugs to get.

Also the check engine light came on . It would come on after running full throttle while I was slowing down.

Anyone got any ideas? I gotta run the codes to see why the light came on.
