the car in park with pedal to the metal will hit 4500rpm max and it does that very groggy has good MAF, injectors, compression ect also smokes a bit from the oil filler cap when you take it off and after it warms up it makes a slight ticking (sounds like a backfire i think) and smells of gas my engine check light turns on and goes out intermittently then when i run the computer codes i get a 2341 and a 2342 both have to do with the o2 sensors yet then i reset the computer and had them unplugged and got the same groggy engine and even though they were unplugged i got no check engine light is my computer bad? where is it located? ect any help appreciated -thanks ---cliff

 

i actually have not checked fuel pressure it seems to be fine for the injectors on the left even with the right ones unplugged it still runs poorly then if i unplug one on the left (near the fuel in line it putters and dies could this be bad fuel pump? could this explian why the computer says everything is fine?
