HELP. Please…

After doing a bunch of work my truck seems to run 95% perfect. The only thing it does is want to stumble when I give it some throttle. When I ease into the gas very slowly it wont do it. Any suggestions are very appreciated. It is driving me nuts. Thanks!!

What work was done? Seems like a fueling issue to me .

 

Timing belt, spark plugs, and injectors. I agree it seems to be a fueling issue. Old fuel pump csnt keep up with new denso injectors?

 

Clean the TB

 

Where'd you buy all your parts from?

 

Thanks. Cleaning it now. All oem parts from eBay and other online Toyota parts dealers.

 

OEM parts from eBay could be counterfeit.

 

That is where I was going with this. What did you buy from Ebay and from what seller?

 

Hmmm? did you clean the throttle body with a spray down its throat? Saw a vid awhile back that this can lead to problems if this spray washes carbon into the lower and adjoining IAC.

Found this vid helpful in taking these parts off to clean them.

Oh best to be prepared to R&R both gaskets. Suggest you have on hand a new gasket for both throttle body and IAC as the parts removal may damage the existing gaskets

Also information on TPS may be helpful.

Hope this helps, good luck. Woodcutter

 

Here is what I got.
Just now seeing something… spark plugs say for 00-04. Mine is a 98 does that matter??

 

I took the throttle body off to clean. IAC did not want to come off so I gave up because I didnt want to strip the screws. Should I try again and clean the IAC?

 

I use needle nose vice grips when those screws start to strip then I replace them with allens.

 

Thanks Woodcutter! I live close to you, any Toyota mechanics you would recommend? New Toyota owner.

 

Unfortunately, no

 

pretty sure the IAC screws are JIS screw heads and not Philips. And they are on there TIGHT!

EDIT: use an impact screwdriver as well as the correct bit. I don't have an impact screwdriver so I put the bit in and smack it several times pretty good w/ a hammer and was able to get them to loosen

 

Awesome, thank you.

 

The weird thing about all of this is that 2 weeks ago before I did the work the truck ran great. That's why I'm thinking its something related to what I did. Bugging the crap out of me. Prob something small and dumb that I keep missing.

 

If I was still out that way I'd be glad to look at it for ya. Used to be stationed at MacDill AFB from 15-22. Still have property out in Riverview. Do you have IG? I have a couple contacts that may be able to help you out.

 

Awesome man thank you. Yes I do, my IG is its_wesleym
