Miss and engine light on after running high idle setting
 

Tuesday I let my truck run on the high idle setting for about 10-15 minutes to keep ac cold, had some meat in car and had to make a stop, anyway, when I came out the truck was missing and the light was on...I cut it off a few minutes later and restarted, the light went off, and the miss gone for the next five miles home. Today, the miss is back and the engine light??? Any suggestions???

This is an 02 with a TS 6 position chip

Get the code pulled. Possibly a UVCH problem (lose connection).

Got the codes pulled yesterday...
P1316, P1211,P0541, P1876, P1832

It showed on a cylinder camparison test that 6 & 8 were acting up, you can barely tell it is missing at idle. On the buzz test, only no. 6 injector barely buzzes compared to the others...now that I have an idea which one I will pull the drivers valve cover and check the harness.

It was the plug loose under the valve cover :happy-dancing:
