Re: Throttle Mashing hesitation?
Interesting, Sounds like the majority of the responses are cycling back to the TPS (which I have never changed in mine) Also for safekeeping I might as well change the fuel filter, as by now most of the debris have prob been sucked up through the fuel line and partially clogging the filter. (Would anyone recommend changing the MAP sensor too while I'm at it?)
And to Tony, the truck is giving a "Service Engine Soon" light after it has been running for about 10 minutes, I haven't had it checked but I'm presuming its lean codes from all the engine mods I'm running, the fuel pressure usually goes up once the engine is at normal operating temp.
To Tennes. I double checked the fuel pressure today when I mash on it, no sudden changes in pressure, the gauge holds steady.
Sounds like a new TPS is in order...
Thanks everyone for their help on this topic, any other suggestions are more then welcome!!
