You have an intermittent no start in other words?

It starts fine. It does not run right. It bucks and does not shift right when it's warmed up. Have checked the wiring and it looks fine.

Any trouble codes in the computer and if so what are the numbers?

Don't remember the code. I have a call into my mechanic who did not have time to look at the truck yesterday. I will reply back when I get the code.

The truck has 147,000 on it but the motor has been replace before I bought it and they could not remember how many miles on it be it was to be lower than what the truck has.
