Hello Dakota bretheren,
It's been a while since my last posting. I decided to seek the wisdom of some people who might be more successful with this particular diagnosis. Basically, the truck warms up fairly smooth, then it begins idleing rough. It drives and shifts fine, accept, always seeming a little rough. It chokes badly, on hard accelleration, around 3000 rpms. If l ease up on the gas, it smooths out. The items I have replaced include a complete exhaust system, CTS, CPS, MAP, TPS, Pick up Coil, Coil, Plugs, cap, rotor, wires. I get know codes on a key cycle. This has been plagueing me for a while. I thought about replacing the IAC, but have been told that should not be a factor on hard accelleration. Does anybody have any knowledge on this? This forum is always very handy. Thanks in advance.

 

The IAC Idle Air Control valve will be the problem with bad idle. For the shifts you can adjust the TV cable, Check the FAQ in this section for a how to.

 

Thanks for the quick response. I guess I'm not familiar with what you mean by TV cable. It seems like the engine is coughing very badly on hard accelleration, but I'm assumming you believe it's a actually a shifting problem? Thanks again.

 

Not only am I not familiar with what a "TV cable" is, I don't see any referance to it in FAQ. Can somebody, please, give me a little more info? Thanks again.

 

Here is a copy and paste!

 

Hello,
Thanks for that link. Unfortunatley, that did not seem to do the trick. The truck seems to cut out, just revving it, around 3000 rpms. Perhaps the throttle body is just pretty clogged. Also, will a faulty IAC cause bad fuel economy? Happy Easter
