Still working on the 1994 dakota mpi fuel injection. No codes are present at this time. Installed a new coil and the truck is still popping in the exhaust, down on power, dropping at least one cylinder. When the engine is cold it appears to be idling fine. I did not test drive it cold. I did test drive hot. I plugged off he vacuum lines for the egr valve, disconnected the power line to the egr with no difference. I didn't mention previously, this is a rebuilt engine with 10,000 miles ago and I did a compression test and all cylinders are 150 psi. I even checked the flex plate to ensure there were no cracks that would throw of the crank position sensor. Any suggestions what to look for next?
