I don't really know how to explain this, may be why i couldn't find anything in the search but my truck 92 22RE runs fine at idle but sometime not all time when i'm taking off kinda fast after i shift from 1st to 2nd and push the gas it seems like the moror will bog down. I can let up off the petal and it will speed up.. Does not do it everytime but will do a couple times everyday.. Any ideas?... no check engine light, 28-30 mpg

I wonder if you have a TPS going bad...not sensing the correct throttle setting & going haywire for a second....

Mine does the same thing every morning at exactly the same time on my way to work. After that it's fine all day

If it only does it when it's cold, I'd bet your cold start injector is going bad.

Robrt32

I know my cold start injector is bad.. I have to use either in the winter.. Mine does it when its warm.. Ive never noticed it in the mornings when i take off

I'm curious about this as well. My '92 has the same symptoms, hot or cold.

Robrt32

Bump it back up, in case somebody missed seeing it

gametom

mine has the same symptoms but it is in a warm start condition and i'm only getting 14-16mpg

Robrt32

So is this something you have to just live with on some yotas? There seems to be several of us with simular problems..

gametom

i have brought my truck to a stealership they told me leaky injectors and that it needed a tune up. the cap plugs wires and rotor have less than 30k on them and everything is ome so even the dealer is unsure of the problem

i Will find the problem

I'm like you , I know all my plugs and wires are good.. I have not been long ago worked on my injectors.. I don't believe thats it either.........

gametom

my latest thought is the fuel pressure regulator. i don't have a pressure gage but i am going to try to track one down this weekend. the resining i have for this if it is stuck the pressure may be to high and there for dump added fuel into the cylinders flooding it

not really sure but if its cutting out when you step on it couldnt that be the fuel filter? just a thought of something to look at

I have a similar problem when it is cold in the morning also get a stumble when it is raining out or high humidity right after it rained I was thinking it might be my MAF.
I have new cap,rotor and wires & plugs and it is still running funny

gametom

my fuel filter is about 2 weeks old so it's not that and my original was fine but you only can tell after you take it off

test your ignitor mine had similar symptoms when it was bad expect it was random times not cold or hot

gametom

i'm not sure what you mean by ignitor can you clarify
thanks

CyMoN

your igniter coil is the thing that provides spark to the distributer
