On my truck I have had this trouble off and onI have put 2 coil pacts wires plugs biometric sensor 3 Temp- sensorscleaned the mas sensor replaced the 2 sided module and the ECM. What this thing is doing is runs great here in the yard untill I go about 2 blocks then the check engine light may come on or not but #1 cyl. And #2 cyl won't hit. I have good fire coming out of the intake side coil pact. The exhaust coil pack my be firing or not does'nt effect the running either way. Also some times out of the blue it will clear up 1 to 2 miles then the same thing. Like going into limp mode now when dsl connector is jumped it flashes steady like no codes or does not blink at all.I put a timing belt on it about 2 months ago and it ran great till about 2 weeks ago it had a mark on the bal, shaft gear they are saying thats the cam sensor. Ran too good. The cat has been removed this county does not require emissions Inspections. The o2 sensor is way far forward so I can't see that as being the problem. I can sqweeze the air tube right at the throttle body it acts like it might effect theidle then starts run ning ok. I have worked on this thing more than I have customers cars HELP
