98.5 loosing power
I have had my truck for about 3 months and i have noticed a loss of power.
I can be going up a hill and mash the pedal and not speed up at all. it just fills gutless on flat ground or a hill. I have changed the fuel filter and air filter. it has 260k miles on it could it be injectors/lift pump/ injection pump? Any ideas? |
it sound alot like the tps(throttle position sensor). the best deal is on ebay for less than $200 brand new and that is the cheapest i have found them
|
what are your fuel pressures idle and WOT?
|
How can you test the TPS?
I will have to get a gauge what should they be? |
Does it sound like it is trying to go but just doesn't make the power? or does it blow lots of smoke when you mash the go pedal? if so check that you haven't ripped or blown loose an intercooler boot. It probably is the tps, but i would check the cheap stuff before spending $200 on parts. But i'm a cheap-:moon:
|
it sounds good just no power. and no smoke at all. i will start checking stuff.
|
i bettcha your lift pump is worn out. prolyl about 0psi at wot, better look into it soon. if it is fuel pressure you can kill the vp44 pretty quick!
