Hello,

I bought my vehicle used about 5 months ago and luckily it still has manufacture warranty however it is due to expire on Sunday.

Lately I've noticed that my truck has this big jerk when I switch to Drive or Reverse from being parked all day or night. Also noticed that while I have been driving and after being idle sometimes the engine sounds VERY accelerated. So loud that I can feel it as Im driving and hear it with music on.

I took it to get serviced and they did find a problem with the transmission so I thought both problems were related to the transmission issue. Wrong, I still have the acceleration problem. I had the problem again yesterday and I had already been driving for about 25 mintues. I stopped at a red light and when I turned I heard the loud accelerated noise again. My truck is still going but I failed to look at the RPM Gage to see if it was going high. I also noticed since the recent repair, that it seems as though I am having to press on the gas a lot more while I am on the highway because I feel like if I dont have my foot down on the peddle hard enough it decelerates. I don't know what could be causing it!

PLEASE HELP!

First, before the warranty expires, call them and tell them there is a problem so it is documented prior to the experation of the warranty. Next, does the noise you hear seem to happen after you have been at a light for a few minutes? Does it sound like a whirling or fan sound?

It sounds as though I am trying to hit 70MPH in less than 10 secs but I am only slowing accelerating to maybe 15-20MPH. Thats how loud the acceleration sounds. It isnt making any other noise and I doubt it's the fan.

Is it likely that a fuel pump is involved? Or the fuel pressure? Would this problem show up as a code if they run the machine through it? They are telling me that can't do anything until the technician can duplicate the problem so they know how to proceed.

I honestly doubt the fuel pump has anything to do with it. When you hear the noise, is the engine actually reving or does it just sound that way? I wonder if the transmission is slipping.

As far as checking for codes, fuel pump pressure won't set a code. However, if the pressure causes the engine to misfire, it will show up as such, "Random Engine Misfire."

I spoke to the advisor who did the first repair with the transmission - he repaired a part called shift selenoid. Anywho, I spoke to him and told him that one of the issues I reported wrong the first time was still happening. He mentioned that possibly not enough air going in through a fan at low speeds etc? I can't remember the words he used.

Any idea what he may be referring to?

I am sorry, I forgot to mention that yes, the engine does sound like it is revving because the truck is in motion when it happens and the last time it happened I noticed that it wasn't allowing me accelerate past 20 until it stopped sounding like that and it continued. The revving only lasts about 10-15 secs. At low speeds.
