hey everyone ive got a 88 pickup, xtra cab, 4x4 and the thing recently started running like .

it starts up fine. idles fine. but when i let out my clutch to start moving it sounds as if it begins to misfire until i get to about 3 thousand rpms then it runs fine. if i just try to give it more gas it makes a pop noise. last year i replaced the spark plugs. wires. distributor so what do you guys think? thank you guys for taking your time.

id do a process of elimination and disconnect 1 wire from the cap at a time and see if there is a running difference when you rev it up (actually does it rev up fine with out a load?). if it runs "crappier" then it did before when you disconnected the wire then chanses are that wire or spark plug is good....BUT if it runs the same while you have a wire disconnected then thats your bad wire or spark plug. mine did the same thing and it ended up being a cracked spark plug that made it misfire backfire and have no power

ya if i just rev it when im not in gear its fine. i called my buddy and he seems to think my mass air flow sensor if dirty. so he said to pull it off and blow it out with an air compressor

do you have a check engine light on?

RompKing282

ya but its been on since i got the truck 4 years ago. the check engine light only turns on after 30-40 mins of driving

hmmm well id do a self diaognastics test on it. to do that let the truck warm up to normal operating temp then turn off but leave the ignition on. pop the hood and rite next to the fuse box there will be a diaognastics plug...you have to jump e1 and te1 and then go inside the truck and your check engine light should be blinking. How ever many blinks is your code number....sample....if you have a code 21 is will blink twice and pause for a second and then blink once and then it will pauce for about 5 seconds and start over and if you have more then one code it will be folled by the 5 second pause

RompKing282

when you say "jump" e1 and te1 what do you mean?

t-1hundred

i mean get a wire or a paper clip and connect them both

RompKing282

oh.haha i thought it was something hard

t-1hundred

nope lol

so i havent done what u said but i checked all the spark plug wires and it seemed to run ok. i also tried to check what cylinder wasent firing by pulling off the plug wires and as i was pulling them off i noticed that the 3 that i had taken off did not change the sound of the truck. i dont get it.

RompKing282

oh and i made a trip to the gas station so i could put injector cleaner in the tank. still runs like crap

t-1hundred

well when you pulled 3 and it didnt run any different that might be your problem there.... follow the wire to the spark plug it goes to and pull the spark plug and inspect it

RompKing282

today we went through and re checked the plug wires and nothing has helped. we tried to "jump" e1 and te1 and i dont have a te1. tomorrow im going to take out all the plugs and figure out which one is rich from the misfiring

tktmsa

There's your problem right there - no TE1 terminal! :7)

RompKing282

maybe im looking in the wrong place. i looked in the little box by the fuse box.

Get a manual, or somebody post picks of where the jumper goes. If you buy a manual its in there in detail, and it gives the code description..

Im curious about this as my 22re sems to have the same problem, but I havent been able to work on it. if its not the plugs, someone mentioned to me about the Throttle Position Sensor. Let me know what fixes your problem

RompKing282

ya tonight i swaped all the plugs and they look fine but im takin it to my buddys uncles shop in the morning so hopefully i will have some good news

RompKing282
