i'll look into the MAF, i just got a code 43 so now my TPS gotta change.

sorry if im being a noob but i jus really want my truck on the road. ok will the TPS make your truck have a hard time starting??i know it'll run rough and idle rough but will it make the truck have a hard time starting?? i just got rid of the other codes and now this one.

i've tried the 02 sensor and still the same. i'm not sure what it is but it's fustrating. thanx guys for the help and advice if there is any more advice keep'm comin. thanx again.

truck runs when cool but once it warms up in temp. it starts to bog out like faulty plugs but i changed my plugs and wires. maybe the MAF is broken but how do i check it?

hmmm heater in the MAF? ok so how do i check the MAF? what should the normal readings be?

ok reset ecu still same results. umm how many heat sesors are there? askin cause it acts up when warm and running for more then 15-30 min.

nope cant go over 3000rpm. ecm give code 55 so now i'm lost dont know what to look for now.

well i relocated the knock sensor and the code went 55 but the truck still runs like crap. could it be the oil?? i had it changed at a lube shop befor all this happend and it started runnin like crap the next day. i think they put 5w30 is that to thin? i usely use 10w30 on all other cars.

to relocate the knock sensor where will i find the old knock sensor wire? what color? i have a 91 vg30e.

regular gas from chevron. but i'm kinda leaning towards the knock sensor.

my 91 starts up fine when cold then drive for afew miles to warm it up then turn engine off wait five to ten min. and it won't start then wait bout an hour some times longer then she starts up. that's one of my main problems besides the bog at 2800-3000rpm.

wat does it mean? i changed my dizzy, rotor, plugs, and wires just a few days ago.

wil the knock sensor make the engine run rough? what are the symptoms of a bad knock sensor? and is it a simple fix?

ok i got a code 34- knock sensor. will the knock sensor make the engine act this way?? if so is it an easy fix??

i swear there was a topic on this but i can't find it so i guess i'll ask it again. my 91 pathy bogs and missfires @ 2800-3000rpm and will not go pass that. i changed my dizzy, rotor, plugs, wires, feul filter and feul pump also cleaned the MAF. what else can i look into that might be the problem

i have a vg30e and i'm no mechanic so i need info on where to locate it .
