Stutter when warm?????

[jamesf6943]

Hey Guys,

I am at a bit of a loss! Recently while driving I suddenly felt a drop in the engine (like only 4 cylinders were left). I limped the car home and pulled the codes. The scanner indicated Cam Position Sensor. I changed the sensor and also dealt with the intake leak. Since going back together nothing has changed.

The car starts first time, ticks over perfectly, runs until up to temp, then misfires and will not go above 2000 - 2200 rpm. I am also pulling misfire possibly due to bad catalyst?

I have pulled the MAF and TPS while running and got a response indicating to me that they are working?

Any information would be greatly appreciated. I have searched and found similar problems, but the threads just seem to end, either the problem fixed or continued headaches?

Thanks again!!

Post the code up here, they are always useful in searches.

Cam shaft sensor ? or crank shaft sensor ?

The codes indicated cam shaft sensor. Through some of my reading others have found that if the cam sensor goes, the engine will still start, if the crank sensor goes it will not? I am not sure if this is true. I was however wondering if these symptoms could be caused buy O2 sensors?
