while traveling down the highway yesterday. All of a sudden something im assuming was a backfire when pow and from that point on I could not press the gas and accelerate any more. It will crank and idle and I can baby the gas and get it to rev up but not like it normally should. Their is no catalictic converter so that's out. Its straight piped to the muffler. any thoughts.

 

Sounds like it could be the mass Airflow sensor and possibly the idle air control valve.
-Try and start the car with the sensor unplugged and see how it idles.

 

the truck wont hardly idle now and run, would you maybe think about the fuel pump being an issue

 

Could be a fuel pump issue...but the Mass airflow sensor does tell the computer how much air is being sucked into the engine, thus regulating how much fuel goes into the cylinder. If the fuel pump was bad i don't believe you would be receiving any fuel to the cylinder whatsoever. Have you ever replaced your timing belt? The reason i ask is because it sounds like something that regulates the Air/Fuel mixture is bad, whether it is a sensor or a timing belt.
Good luck man, I hope you figure it out

It quit running all together and it was the fuel pump so the fuel pump and sending unit was replaced. Tks

 

Glad to hear the problem was resolved! I must have misread the posts, because i thought the car would only do a rough idle. Hope it runs like a champ
