1982 2.4 swapped runs like its skipping.

[Salteen]

Ok so a freind of mine has a 82 D50 2wd with a 2.4 out a newer truck. Its fuel injected. It runs like it is skipping but we have replaced the injectors, plugs, wires, and distributor. Any suggestions?

any help guys?

[pennyman1]

is it carbed or FI?

[Salteen]

i told you, its FI, its 2.4 swapped 1982

I can only suggest testing each injector socket for pulse and look for anything that might indicate either intermittent injector or spark failure. If you have a broken wire somewhere in the injector loom, the constant vibration will cause it to break circuit. The DSM guys always struggle with fragile harnesses.

ok i will tell him, thanks! :D

Other thing to add - always try to get engine error codes from the ECU. It will more often than not identify a fault or at least give you a hint at what is going down.

will do

also check the ecm for bad caps - they fail and cause all kinds of poor running issues.

It was actually a bad ecm cap, good call pennyman!
