Hi I’m trying to figure out what’s wrong with my z not sure what it is. It has 126k miles had the spark plugs and coil packs replaced at 120k miles(less than a year ago) just replaced the valve covers at 126k miles. No problems with fueling. Just replaced both camshaft positioning sensors and also the crankshaft positioning sensor. Also feels like the car is in a limp mode and won’t rev past 2k rpm’s if I’m driving but with rev past that if I’m stopped and in neutral. Also feels like most if not all cylinders are misfiring. And did a compression test and got 170psi in all cylinders. Any help will be appreciated…

update***had a place diagnose what was wrong with it, my catalytic converters ended up being clogged

 

Make sure you have coil pack connectors right

Easy to swap 4 and 6

 

I see no mention of pulling codes. Has this been done? What prompted all the parts replacement (ignition side anyhow)?

 

the thing is at first I had no codes I do now but don’t have an obd2 reader on hand I’ll let you know what that code is once I get one
