There are two common problems with your truck.
The intake manifold leaks coolant into the intake runners.
The SCPI system fails all the time.
If it's just one cylinder having a problem you can buy one poppet nozzle for about 70.00.
But if you have more than one cylinder acting up, I suggest you get the MPFI change over kit for 350.00.
