My car runs rough on idle and has poor acceleration. but my compression test at the dealer came back fine. I'm leaning towards the fuel pump. When I go too fast, over 90, the car kicks back like there is a governor on it and the engine light flashed for 0 seconds, but any constant speed under 90 and the car runs smooth and has no problem. Then back to idle and it wants to stall but never does, then sometimes at idle its so smooth I cant even tell its on. I've attached a few screenshots of my OBD reports off my computer, maybe someone can tell me.

 

Looks like your coolant temp sensor is fubarred....it is reading low if the car was up to temp

You likely have a vac leak

Your air pump system has issues....is it still installed?

One of your tire pressure sensors is not working

You have a problem with the cooling fans...need to check that out before you overheat

Something is up with the charging system...unless you just killed the battery and it is charging hard...your voltage is high

 

Vacuum leak, or a leak in the air hose between MAF and throttle body. This will confuse the ECU.

Or, fuel pump. Things like year, mods and miles will help diagnose problems.

 

Take a look at your exhaust system if the suggestions other members have made don't help.
