Injector work interminttently

t happen again at around 190 degree temp. I try and switch the wire on the injector that was not working, and it worked, so my injectors are good. When this happen I had a chance to slightly tap on the ECM and it stop. Ok now does this mean i need a new ECM or just a bad connection. Your help is greatly appreciated.

If tapping the ECM fixs the problem, try reseating the connectors and the chip. If it comes back I'd replace the ECM.

replace your ecm ,seen a lot of ecm problems like that

Isn't it called a VCM now? the ECM is the older terminology but they are the same thing, actually now they have a PCM as well.

it depends what year it is you have ECM, VCM PCM,PCM b ,PCM c, just to name a few also you have BCM , TCM Tccm, and so on
