Mostly on the highway my 1994 22re will suddenly loose power. It will go fine but then it feels like i hit a wall of wind and i loose about 50% of my power. The rpm's stay the same and it doesn't make a difference if i floor it or even down shift. I have a K&N air intake that is clean, the exhaust is close to new and the cat is new. I replaced the plugs and the fuel filter to see if that would fix the problem but didnt. Has this happened to anybody else? Anybody have any ideas?

Have you checked all your belts, and what else happens when you lose "power" does anything dim? any noises, shakes or knocks?

PWDR PG

My alternator belt is a little loose right now but this problem was going on before that. And nothing else really happens when the power dies out. It doesn't seem like an electrical problem because nothing dims, there is no knocking or pinging either. It just feels like it runs out of gas or something but then it will kick back in and go fine.

clutch or a fuel delivery problem maybe the fuel sock on the bottom of the fuel pump in the tank

TacomaTRD

check your cat, it maybe getting plugged

I'll have to check that fuel sock. That sounds like it could be it, at least I hope its something simple like that. Is it hard to get to On a 94 pickup??

Is this only at full throttle?

PWDR PG

Yeah I only notice it on the highway when I'm at or close to full throttle. I have 32X11.5's with a 4 banger so I'm pretty much all the way down on the loud pedal on the highway. You know what it is Dragr1?

this is kinda weird because i was just going to post the same thing thats happening with my 87 p.u with a 22r...

Sounds like the maf (mass air flow sensor), at least that is what it was on my '99 with the exact same symptoms. If it isn't that, then try the throttle position sensor. I would bet it is the maf though.

brendonv

does a 22r have a mass air flow sensor?

PirateFins

No the 22re has a VFM (vain flow meter) the more air pulled in, the further the vane opens, and moves a potentiometer that sends the signal to the ECU.

PWDR PG

thanx, i'll take a look at the MAF (or the VFM). Whichever it is on my 22re> I'll have to check the book.

Sorry, I'm not that familiar with the 22re, just the problem sounded exactly like the problem I had.
