22re running with miss
So I got a change to work on my truck and figure out what was making it run odd.
Before it would idle fine and rev stationary fine. Upon accelerating at low rpm's the truck would seem like it is missing or hesitating. But once it got to higher rpm's the truck would just take off.
Well I checked the AFM and seemed like it was not moving freely so, sprayed some stuff in the and drove it around. problem solved, or so i thought. I drove it for a bit, parked it and went to start it up 20 minutes later and back to the old problem.
Now it seems like even the idle it rougher, and revving it stationary it seems to miss unless I ease into the throttle slowly. It does this same thing driving.
Possibly TPS? Or did I ruin the AFM now?
Has anyone had this problem and found a solution? Ive read multiple threads close to the problem but havent found a sure solution.
Ive heard of replacing the AFM or TPS, and then completely doing a tune up (plugs, cap rotor, wires)
And plus being a college kid its hard for me to spend the extra money replacing everything in hopes of sucess.
Any other info would help alot! Thanks

check for vacuum leaks and check the intake duct for cracks in the boots
check and set your timing
look for any loose connections around the coil and for any spark plug wires that may be rubbing against things.

Try going over your last steps. Think to yourself "where did I put the motor?" Maybe get a metal detector and walk around and see if you can find it.
I'm drunk, and that sounds so funny to me right now, so yeah. We'll leave it at that.

"My 22re is missing. I could've sworn I left it in the truck...."
I was refraining for saying that but since someone else broke the ice....

Check main intake hose for cracks and leaks. Vac lines. Tune-up? Check more into your AFM. Do the resistance test. IF its out of spec anywhere its "technically bad" but still useable. Dirty air filter?

well your, on the right track.. plugs, wires, air filter rotor, cap, rotor button, fuel filter is not a waste of money its called preventive maintenance.. so its money well spent.. right..
just make a things to check list and you will able to figure out what is causing your problem

Well to revive an old thread. I tried cleaning the inside of the MAF, and my friend insisted we spray this stuff (idk what it was called) on the inside of the MAF and it seemed to fix the problem. I took it for a drive and she went like a bat outa hell. Well I parked it and went out to start it up again maybe 15-20 minutes later and back to the same problem. Now maybe even worse than before
So by doing this did I kill my MAF?
Has anyone had problems like this with it? Or can you clean it?

Yea Junkers I did mean where the air goes through. And it would makes sense to me that is would mess things up if it wasnt moving properly. Is there anything you would recommend to clean it with (anything special or just some soap and water)?
Would it help to clean out the circuit board area at all too? Just like hit it with some compressed air?

I would think that something like throttle body cleaner would work and maybe a tooth brush? I guess it all depends on how dirty it actually is in there.

Post 3 also mentions a ohm meter... And I'm sure he can find in the FSM how to check the MAF...
I was trying to give the poster some cred, but yeah it's a little out of context...
Still: Ohm meter > FSM > MAF

let me know what it ends up being. i've got a very similar problem and i've already replaces plugs, wires, cap, fuel filter with no luck. i've got a new fuel pump to throw in for a starting issue that a mechanic diagnosed. maybe it will fix both, fingers crossed....

Alright, Well I cleaned out the MAF (where the air goes through) didnt seem too dirty, but now its really clean.
I also cleaned the air filter (K&N) so thats alot better too.
I started it up and it went to a cold high idle and it seemed fine. Nothing sounded out of the ordinary. I let it idle for a bit and i revved it and it and it went through the rpm range fine. I thought to myself sweet, I fixed it!
Well, I figure ok its running good so i just let it idle. After its been idling for a while and its up to temperature, I go to rev it again and it stumbles and sounds terrible.
But if i ease into the throttle the problem doesn't happen.
Im still really confused, I did not how ever do a resistance test, I will try and do that tomorrow.
Any one have any other ideas or have a similar problem?
