If the car runs, it cannot be off by too much, like fixkick says on his pages, the best way to investigate timing being off is by using the timing light, I marked the crank pulley on all 4 firing points and watched it as it cranked, only then I found out I was timing my distributor wrong, but in my case my Tracker would not even start.
I also found spark issues with hesitation, P0300's, bogging, etc. I bought an used distributor (matching code numbers and everything) installed it but it never landed in the same position when I dropped it in like the one in my car did, I always wondered if the small gear at the bottom of the distributor slipped off its original position.
Did you carefully check all your wiring leading up to the distributor? no loose wires at the base of the plug that connects to the distributor base? wiring in our cars SUCK!
Sorry just rambling my thoughts here, I never had P0340 before (knock on wood) I wish I could be of more help.
No i have not checked out the crank key yet, I have a new water pump, timing belt and tensioner to put on there i will have a look when i get into that.
I wonder if a shredded crank key would cause the mostly terrible occasionally ok running condition of my car.
I have not done the run through with the multimeter yet, i was close to it yesterday, but was not prepared with proper pointy instrument to backprobe the connectors.
What gets me is how well the car seems to run after it comes out of a heated garage, good running is maintained until cool down time and then restarts means the return of all troubles.
cold idle control valve, did not, in the end improve cold starts for me either. all that work for no gain.
Spent the night researching cam and crank sync. timing light shows all good, perhaps i have misled myself into thinking all is well in the timing department, but I continue to second guess myself. I guess its time to take off the belt cover and take a look.
And then check the wiring related to the cam position sensor to ensure all is in spec.
I will solve this problem.
thanks for your thoughts
