04 Tacoma Throttle Response Prob?

Hey guys,

My Co-worker has been having a recent problem with this 04 Tacoma. He said after he drives it for like Half hour or so he will get no throttle response. He will press the gas down and it wont go nor will the RPM rev up. It just wont respnond unless he slams the throttle. Sometimes if he lets it cool down for a bit it will go again and then it repeats itself. The dealer replaced his whole throttle assembly and it still did not fix the problem. Wondering if you guys had any suggestions or any experience with this problem on the first gens. Of course he doesnt have TW so I said I'd hit you guys up for him and said GET TW!

 

No check engine light? I wonder if his throttle cable is binding somewhere. . .

 

I have similar symptoms with my '03 in the past. Early on, when running at high speeds over 55mph I would lose revs and speed very briefly. It was scary driving down the highway and the truck would decelerate on me. The dealer diagnosed that as a faulty TPS and said the WHOLE throttle body needed to be replaced in order to replace the TPS. $1200 later, that problem was solved.

I also had an issue where I could not accelerate from a stop light or such. Really sluggish, it would eventually get up to speed, but, I felt like an old lady driving. Ran horribly as well. Never popped a code. But the dealer figured out I had bad catalytic converters. And it never popped a code!

In order to test his theory the mechanic took the catalytic converters off and drove it to see how it felt. Yeah, loud as hell, but that was the problem. Replaced both with Magnaflow direct fit, bolt-ins and have had them on there over 18 months with no codes.

Hope some of this helps

 

Hmmm. Wonder if hes having the same problems as you had with that 03. Thanks
