Any codes? Lights on dash?

Throwing out an easy one - pull the MAF connector and see what happens.

Pulled maf plug nothing happened. Traced wires found splice,reconnected 2 that had come undone. Tried again and it stalled. Maf good now but still stalls when not given throttle then will idle until it gets to temperature then it starts spitting and sputtering and goes into limp mode.

Sounds like a vacuum leak somewhere? Trace all the work and surrounding area to see if you didn't put something back or caused a hose to crack.

Sprayed starting fluid around everything,throttle body,hoses,injectors,intake,no response. Seems to be ok in that area.

Have you tried cleaning the ETM?

Did either make any difference or did the problem start after you installed one or both?
