Need help 2001 1st gen taco 2.7L

I’m currently having a problem with my truck. Out of no where it just idles at 3K RPM and redlines at 3100RPM. Help would be appreciated, thanks!

 

Throttle linkage stuck?

I had both the fire wall crack and the throttle body just get far to dry and hang up.

Massive vacuum leak?

 

It’s neither, I checked everything and it’s good. I also forgot to mention that I cleaned the throttle body and all the plugs connected.

 

Some place your getting way to much air into the engine.

Good seal when you replaced the throttle Body after cleaning?

No cracks in the air intake hose?

What happens with the Throttle Linkage disconnected ?

What codes have you pulled?

 

yes, I sealed the tb with gasket maker and seal. I don’t think so, I sprayed the hoses with starting fluid and didn’t have an idle jump.
Throttle linkage when disconnected will make the truck die
For codes not too sure
(Also when I unplug the maf sensor, the trucks suppost to die but it doesn’t. It still stays on)

 

What do you mean "not too sure"

You have codes or you don't, did you check?

That's the first thing to look up before posting for help; here we're guessing, with codes it can help you narrow down your issue.

Since we're not sure, you sure your gas pedal isn't sticking? Do you have to pry it up with your foot?

 

Out of nowhere, or right after you cleaned the throttle body? If it’s shortly after cleaning the throttle body id take it apart and make sure none of the vacuum passages are clogged, cleaning it tends to do that.

 

Yea my gas pedal isn’t sticking. I tried it just to be sure and it’s still the same . I will try to scan the code today

 

Invest in an OBD tool; nothing fancy either just a cheap one.

I have like 3 of them, 1 in one of my cars and 1 in my wife's, and a 3rd that sits in my tool drawer in case I need to check codes for other people.

They're super cheap on Amazon and work well for basic stuff.

 

Yea that’s what I did, I took everything off the tb to clean it . Once dried I put everything back together

 

I have a reader, my family member is currently using it. So I will check it out once I get it back

 

Vacuum leaks would be what I'd chase.....

brake booster and pcv are both troublesome in aging tacos...


NExt I'd scan and look for live data on all the engine sensors and see if they're in correct range....

could be that one of them is just unplugged....or bad grounded....



Mass air flow sensor should of cleaned from the start gate....when any engine changes are felt....
keep a can of that on speed dial....

 

What has me thinking mechanical is the limited rpm range !

Then when OP disconnects the throttle linkage the engine stalls.

Really points to a cable malfunction plus other problems.
