Cam sensor issues, I think.

[dsheps83]

not a turbo but doesn't matter, I have a 2003 ba fairmont straight six

car was getting really sluggish and sounded like it was struggling under load, also running very rich. and now has gotten that bad that when it struggles under load it stalls, taking off from a standing start fast or slow it would die around 1500rpm then just stalls, takes a bit to crank over to start again.

I pulled the rocker cover off noticed the cam lobes had been worn down, had a second hand set so dropped them in.

changed the o2 sensor, changed both cam angle sensors and changed crank angle sensor cleaned throttle body. swapped out spark plugs and coils. and now the oly way I can drive it is by unplugging the cam angle sensor ion the intake side but it doesnt run well at all.

the errors I get when I scan it are

 

p0340 which shows as camshaft position sensor "a" 

p1340 which doesnt show but a google search shows it maybe be camshaft sensor "b"

but I replaced these with working ones of another car. could my computer be screwed? is there a way to test wether the wiring to the sensors is ok

 

cheers for any replys

Hows the wiring to the cam sensors especially the drivers side? 

[dsheps83]

When I plug the drivers side cam sensor in it stalls out . Idles fine. Revs in neutral fine. Put some load like drive off or stall it up in gear and it stalls. Unplug the sensor and it droves fine just runs really rich. 

 

Cos it idle and revs fine in neutral I would think the wiring was ok?

Has it got worse since you did the cams etc. or is it basically the same ?

[dsheps83]

nah it got worse before I swapped the cams, I thought the sluggishness was to do with the lobes being worn down. if I reset the computer and have it plugged in, it runs fine for a bit then just starts stalling again. the computer must go back to a base tune then start learning again? about two months ago I washed the engine bay out with degreaser and garden hose, and it ran like crap for days,is there anywhere other than the coils that water might affect?

I have another wiring harness, when I get my other car sorted, I will use the other harness and try and connect it as close as I can back into the computer incase the wiring is dodgy

just to add to this again, if bot cam sensors are plugged in, and I unplug the vct solenoids the car also runs fine, wel like a dog, but doesnt stall atelast.

thought may be it could be the vct playing up. I have another set may swap them out and see what happens, but I didnt se a huge jump in cam angle when monitoring it

I had my car plugged unto the computer and the camshafts are readable.

something screwing going on.
