whats the deal with my truck

[darkhorse1]

Ok heres my prob. right after I start my truck and take off, it starts bogging down real bad ( I mean it will barely go). The bogging makes it shift real hard, then it seems like (don't know if it is related or not but) when its bogging the back driver side brake acts up(locks up sometimes when stopping). Any ideas????? Its driving me nuts!!!!

Your brakes are hanging! Take the wheels off and look at the back brakes.. Wouldn't hurt to look at the front ones too.

it gives a check engine light when it does it, but then it goes out. You can tell its coming from the engine. someone suggested the throttle position sensor but I don't know.

You still should get a code. Post the code for more help.

 

[darkhorse1]

well I changed the tps and it helped a little, but still doggy. I'm going to change the plugs, wires and fuel filter and see what that does.

Will it go "normally" but slowly if you use very little throttle?

If so replace your fuel filter.

ok I've changed the wires,plugs, fuel filter, and the pcv valve along with the tps and its better just still not 100%. Its like it still has a miss in it. any ideas?

Check fuel pressure and compression?

Check compression, and make sure all your plug wires are on the right plugs.

do you still have a check engine light?

ok this thing is really pi@*ing me off. It was doing good, then all of the sudden back to crap. It bogs out then lunges with a ton of power, then bogs, then lunges, etc.......The check engine light comes on when its acting up, but I've had 3 different places hook up and they all said that its not storing the code in the computer or something like that, so they can't retrieve anything. I don't know. Should I try the coil pack and go from there???????

my 99 iszuz rodeo did the same thing and it was a blown intake manifold gasket.

 

[darkhorse1]

wouldn't coolant or something leak if that was the case?

 

[darkhorse1]

could it be my cam position sensor? I'm out of ideas......
Its been raining for days so I can't check anything.
