85 issue, need help!!!
 

Sorry its so long... But this problem started a few months ago and i would be driving along and it would feel like it bogged down a lil. Never spuddered really, just felt like it was gettin all the fuel it needed or something. After about 3 weeks or so of lettin it do that, cause it wouldnt do it constanly only in 1st gear and then pulling a hill. It started gettin worse. It started spudderin and spittin and i would hold it to the floor, when it would get to about 2.5k rpm or so all the power came on at once. It was like whatever was holding it back blew out, but then if u let it idle down a little and got back into the throttle it did the same spuddering agina. So i checked all the vacum lines, they were fine, and changed the fuel filter. Ran great for about a day or so and then it went right back to doin the same thing. So i gave up and took it to a mech. First thing he said it was was someone put the wrong fuel cap on it. Said it wasnt letting it vent or was venting to much, idk, he put a different one on it and it ran great for about 3 days, and then right back to the same ˟˟˟˟. Then he adjusted the tps new wires, clamp was missing on the MAF, he cleaned it also. Ran good for him during a test drive, then when i came and got it it did the same crap again! Pretty sure im missing another trip to the mechanic. But i got another engine in the trade for this truck. He wanted the injectors off of it, so he changed the whole fuel rail. Today picked it up and it ran great for about 30 min and now its back doin the same ˟˟˟˟ AGAIN! But then it would barely idle! I have been just letting it sit till i could figure out the issue or had the money to fix it, and its been sitting for about 3 weeks. Went and started it today and it ran great for about 20min, i let idle for about another 10min and the idle started to get rough again like it would do when it spuddered before. Here is a video i took of it idling after the last trip to the mechanic. I need extreme help here guys...I am sorry this is so long btw

kinda seems like maybe your fuel pump, but i dunno some info about the engine would probably help those who do know more than me to help you. like is it a 22r 22re 3.0 and so one

oh yea guess i forgot the main info lol, its a 22re, and no it wasnt my fuel pump, they checked that. They hooked a fuel gauge up to check it, but i think when they checked it was when it was actually acting right...but none the less he told me it wasnt the pump, and i can hear the pump running when i take off the fuel cap

please someone help me...someone has to have some sort of an idea, O2 sensor maybe?

maybe the idle ajust screw? also have you tried doing a serch? theres a bunch of other people who have had simmilar problems

Have you checked your engine coolant temp sensor? Could cause that. Cold start injector sticking maybe? EGR valve crudded up? It could be a bunch of different things really.

ETA:

Found a link to the fsm for ya

no i havent checked the coolant sensor, can i unhook the cold start injector to see if that fixes it? How do i check or clean the egr valve, and yea ive been trying to search but the only thing i have found so far was pointing towards O2 sensor, it has quite a few exhaust leaks and one thing i read said that could effect the O2 sensor?

bumpin this up....This thing is so damn weird...When i parked it about a month ago after picking it up from the mechanic, it was doin that spuddering crap and would barely idle. So ive just been letting it sit till i could find out whats wrong. Well i went and started it monday, drove it around, and it ran great. Went and drove it yesterday and it ran like a champ again????

drove it all day today and still no problems, but im sure its gonna screw up again. I cant figure why its running right now tho, i havent done anything to it

BUMP TTT.....After doing some more reading its lookin like it could be the coolant sensor team420. The only problem is i dont have an ohm meter to check them.

Rule # 1 of diagnostics... Own a multi-meter, it will be your best friend!

You can pick one up cheap at walmart for less than $15.

Awesome well il pick one of those up. If it is a sensor where is a good place to buy a new one? Ive tried searching and i cant seem to be able to find one? Not make them anymore?

you can get the coolant sensor at autozone....

Oh ok I didn't know that, thanks man

So does the coolant temp sensor sound like the problem? Im gonna pick one up at autozone, have em for $14. Its under the intake manifold right?

can someone straighten me out here....?

if you don't have a multimeter or know how to use one, and start testing things with the aid of the technical manual (1985 FSM that was linked on a previous post) we are not going to be much help.

You are simply asking if it could be this or that, without actually checking anything.

You just gotta test all your sensors for the right readings, testing what the troubleshooting flow charts recommend. come back here with your results if you are stumped after having ruled out a bunch of stuff.....

If you aren't up for this, your best bet is to call around, find a mechanic with a lot of 22RE experience, and send it to him.

keep us posted....

I never said I dont know how to use a multimeter, only said i didnt have one. I have planned on testing these things when i get around to buying a meter. And yes you are right i am asking if it could be this or be that. Where else would I start if I didnt have help from the people on here telling me what it could be. Thought thats what forums were for??? Excuse me for asking questions on tech question section on a forum. I am simply trying to find out what it could possibly be, if no one can tell me anything then how would i know what to look for?
