Car runs great when its cool ,approx. 5-7 minutes.

Once it warms up I have a crazy misfire, like its only running on 4 cylinders. If I stay in it around 4500 rpm the misfire disappears and the car pulls to 5500rpm no problem.

New Bosch 19lb injectors and tune up 10K ago. I'm going to do the fuel filter this weekend and maybe order a AFPR.

Any thoughts.

...I forgot to say that if you rev it from idle in neutral it revs with out the misfire. Driving under load is when its missing. Even at an even speed it doesn't miss only once you start accelerating.

ohm out your injectors, if you find anything lower than 14-16 ohms, replace its but do it when the engine is hot, sounds like your injectors are $hit

 

I'll check them out tomorrow. The injectors only have 10000km on them and were bought brand new

Any other suggestions?

 

checked all the injectors after the car warmed up 15.2-15.4 ohm across the board.

Could a bad O2 sensor be the culprit?
