TPS, fuel filter.

I checked the fuel filter it is still good, unless it has 2 filters. I read somewhere online that it has another filter in it's gas tank.

It?s called a strainer. I doubt thats the problem, but if it became clogged up enough, then I suppose that could cause headaches.

-Check air filter

-Check for loose or leaking air duct between MAF Sensor and throttle body.

-Fuel pressure

-Ignition Timing

-EGR operation for being open all the time.

-Exhaust system (collapsed pipe)

-Engine valve timing and compression

-Worn camshaft

-TPS

Our maintenance vehicle at work had a bad TPS. Stepping down on the accelerator was just like stepping on a ripe tomato.

Don?t know if any of these things are the problem, but its something to look at. Let us know what you find.

I think I hear an air leak, it sounds like it is coming from the left side of the engine. I have noticed a clicking sound the engine makes too, every couple of seconds.

The air leak is fixed but the clicking sound is still their, I was told the clicking sound was a sticky valve. I have checked all the stuff that I was supposed to, and nothing helped. I checked autozone.com and looked at what it said to do. The only thing on it that was different is that it said to check the egr valve. So I checked that and it isn't working, so I am replacing that tomorrow, if that doesn't work then I don't know what else to do.
