Help with 97 XJ6 emission or fuel system problem
#1
![Question](https://www.jaguarforums.com/forum/images/icons/icon5.gif)
My 97 XJ6 4,000 is having a problem starting, was told it is my IAC motor, it chugs and dies and eventually starts, it runs fine after it starts, but the check engine light is on.
I am going to a parts store to get my error codes. I will update when I have them, in the meantime can anyone link me to more info on how to clean this part or something. I really can't afford the work at a even an after market shop, but I do have some experience working on American cars.

If you open the throttle (with your foot) while cranking, does the engine start and run?
The IACV only allows significant air when the throttle blade is closed, You can bypass it by holding the throttle open slightly.
Maybe the EGR valve is 'hung-open'?
That will create quite an intake leak.

Failed camshaft position sensor makes the ECM "guess" as to TDC. Reportedly may have to crank for up to 30 seconds before the computer sorts things out and fires it successfully. After that, running should not be affected. There are threads about the other two codes but they seem a bit mysterious and no one has yet sorted them, from what I've read.

The Cam sensor is used to tell the ECU when Cyl 1 is at TDC. So it needs to be set in the correct position when installed - in the same way as you would align a distributor in days gone by. In fact it's actually installed where the distributor used to be on the older AJ6 engine.
There is a window on the sensor that will show an indicator.
I'm attaching an old "how to" document that I saved many years ago - don't know from where so I can't give the author credit. Hopefully it will explain what you need to do.
