I’d take a look at the maf sensor. Seems like there should be a code popping up. Was it ever recently overheated? A bad head gasket leak can cause similar symptoms. Just tossing ideas out there

No overheating just shakes real hard and dies

Might need the MAF replaced but was aiming toward pump I got crank sensor code and misfires on I believe one side of the engine

When I checked the plugs they all needed to be replaced but the side that has a code had really burnt tips like the person I bought it from just drove the car on three cylinders or sumn

Ignition coil possibly. Have you confirmed spark in all cylinders?

Archangel44 09-06-2019 07:24 PM

No I haven’t but the guy I bought it from said all the coils were new and they look like they haven’t been used much

I threw new plugs in and changed the vacuum things in the front of engine because one was missing

I still need to do a fuel pressure test and figure out how to check spark in cylinders never perform that type of work a newbie with cars kinda

It very much sounds like maybe a MAF problem cuz the car starts every time and just dies out like it gets fuel just doesn’t have proper ratio or sensor failed

I use this it’s pretty easy.

There’s other ways by taking the plug out and then grounding it near the chassis to see a spark. I always get shocked so I don’t like that method. Swap a coil from a working side and see if the miss changes to the new side

I am going to get some more money over the weekend because I’m short just bought a bmw but will get back to you maybe Tuesday and let you know how it works out. Thanks for helping out
