Have a 1995 4runner 3vze starts right up idles fine. Dive it for a bit and the motor cuts in and out. Like no fuel. Starts as a small skip then bigger then whole car shakes and has no power but if I push the clutch in it will rev/idle fine. Stick it back in gear and does the same stuff BUT if I cut it off then back on its all fine. Until while later. Has been happening more and more often. Any ideas? Usually happens when its warm. Injectors clean. New fuel filter. My thoughts are maf.fuel pressure regulator. Or maybe efi relay? Any test I can do? Check engine light won't come one and when I do the dia.
gnostic test there's no codes. Also fuel pump stays running while key is in the on position. But NOT running

Maf. I've had it happen kinda were my 93 wouldn't seem to get up and go. Had to in a way "think" little stutter step before it would go. Once replaced with another oem maf from a 91 problem was fixed. Correct me if I'm wrong but some will say it's vmaf

Fuel pump is going to stay on yes, it's priming your injectors for when you crank it you hear the click, then hear the pump whine, then it should click/shut off, but if it's doing that "constant whine", and not shutting off, there's a problem. There's better ways to check that aspect that these ppl will tell you, but until they sound off, if it were my vehicle, i'd just loosen and pull my fuel line, and make sure there wasn't a continuous flow after keyed "on" but not started. And like edionne13 said, sounds like it could be the MAF, or as it's also called the AFM. I'd check your fuel issue 1st then check the afm. Make sure you have a can to catch gas in, don't just pull the line and spray gas all over the place.

When the key is in the on position the pump never cuts off it will keep pumping. I read another threat with the same thing but he had long start issues. Mine starts up right away. He said he fixed his with a new maf/afm

Edit: not sure if this matters. But truck has no cat.egr.or vapor can. Also cold start injector is bypassed has a bolt in the fuel rail and the injector its self. Was like this when I got it. The previous owner said it sat for 2 years then he got it running he said he was driving it down a bumpy dirt road and it just cut out. I got it and injector were clogged. Cleaned them. Ran fine. Then started yhr skipping and stalling. And has been happening more percistant. After about 20/30 minutes of driving. Or about 2 miles.

My new flamethrower injectors came in today. Should I go ahead and install them or wait till I get a new vafm?
