91 4 runner 22RE hesitation
I have a 91 4runner with 22RE and automatic trans. It hesitates when i punch the accelerator. It does it more when its cold, but keeps doing it even after it warms up. I changed plugs and wires which made no diff. When I advance the timing to where it pings then the hesitation goes away and it seems to have a little more power.
Anybody knows the problem might be?

1. fuel filter
2. injectors
3. check valve lash
4. clean throttle body/ check air filter
5. turn 3 times and whisper "ali shabaz" toward engine
Those are the first things I would scope out... maybe someone else will chime in and give a few more suggestions.

no code
Engine Light never comes while driving and no code is stored. My guess would be if the tps was out it would have a code.
I have also thought it might be the injectors. I will flush them one and see what happens.

Actually AgRunner has a good suspect as well... The tps out of adjustment wouldn't throw a code/ check engine light. In my experience w/ 22re I always check fuel filter first on hesitation, and back the timing off... you don't want all that pinging

Oh yes I changed the fuel filter but not diff. I think its running lean especialy at idle. I read up on the temp sensor and I think its probably the problem. Also I will flush injctors.
Thanks for the help
