VIDEO INSIDE LOOK
Hi everyone,

last night my truck ran perfect and now this morning truck ran ok for the first 5 min then i had a bad stumble in the throttle and idle. today i tried everything but cant find the prob, what does this sound like.....

 

we need more details. what engine? what do you mean it stumbles? is it miss firing? are there any codes?the more info you give us the easier it will be to help you!

 

92 3.0 , no codes so far, stumble like shake really bad at low rpm then even out at about 2500 rpm .....

 

Ok so what have you checked so far? have you narrowed it down I see you have multiple threads going right now. really should keep it all in one thread it would make it easier to help.

 

Sounds like condensation under the dizzy cap.

 

i will check that and let you know....

 

Something else to do is while it's at idle you can pull each plug wire one at a time and see if anything changes. If you pull one and it doesn't change the idle then you have a dead hole which could mean a bad plug or wire.

I must admit here that I know nothing about the 3.0.....

 

nope pulled wires will running and its all good also no condensation under cap......oh yea truck sounds like a lawnmower....

 

video coming soon

 

Here is the vid, I dont know how much this will help you guys help me but it worth a shot.......

I remember last night when i parked it there was coolant sitting on the driver side head where the injectors are seated because i was draining coolant from where it passes through the TB. So that has to have caused some kinda problem because everything was good until it sat over night with the coolant sitting there. so confused.......

 

Crap. That sounds like a head gasket.

 

na i dont think so cause the reason the coolant was there is because of me. will coolant just left sitting there over knight cause something..

 

was there any coolant on any of the electrical connectors? if so I would get some of that electrical contact cleaner and clean any plugs that had gotten coolant on it. WD40 would work also but the actual contact cleaner works best. coolant can corrode electrical terminals fairly quick.

 

i think i might have found the problem, i pulled off #4 wire from cap and there was no difference in idle nothing. i also pulled off #4 injector plug and no change.

 

i did test the ohms on the injector and got 14.9 ohms the FSM 13.4 - 14.2 ohms also #2 injector tested the same...

 

What were you doing when you drained coolant from the T.B.? My 22RE ran really bad at idle and smoothed out at higher RPM's. Drove me crazy for weeks. Turned out to be a significant vacuum leak screwing up the flow through the MAF. Hopefully it's something simple with the #4 cylinder.

 

i found the problem, will post pictures tomorrow, i had a feeling it was the injector(s). #4,#3 were clogged to the max with dirt you will see in the pic tomorrow, i guess thats what happens when you got a fuel filter from 1992 the day the truck was born....I bought the truck one month ago, it was sitting for a year so i did all the basic maintenance. so it went trough its first full tank of gas pretty much today and thats when all this happened. so i knock on wood that this takes care of it. oh ya maybe some suggestions on things to do while i got everything apart........

 

Ok here is the pictures of my clogged up injectors/fuel rail, #3-#4 were fully clogged but i still cleaned them all, runs like new.....

 

Wow!!! Those are yucky...
