Ok guy i tried to find an answer to my issues without posting a new thread but alas i was unable to. Now for the info my truck is a 1996 dodge Ram with the 5.2L v8 when i first bought the truck (2 damn weeks ago mind you) i had to replace the oil pump due to lack of oil pressure now i have fixed that issue but i have another now. when i start my truck it fires up nice runs GREAT UNTIL it gets to normal OP temp. then the issues start i lose all power hit the gas get nothing but a "popping" from what i think is the intake pull the truck over and the idle is WAY off runs like T total sh*t i hooked my code reader up 3 different days and the codes im getting are as follows

day 1- multiple miss fire.. Miss fire cylinders 1 2 & 3 gov sensor high
day 2- gov. sensor again miss fire cylinder 1 &3 multiple miss fire
Day 3 o2 sensor bank 1 sensor 1 system too lean no miss fire

I broke down and took it to the local shop for repair
they tell me the plenum gasket needs replacing "start there" i don't need a Start here line i need to fix this truck ASAP and i'm not payinh them 500 bucks to do it so PLEASE can you guys help out a fellow ram lover thank you in advance

 

Unplug the pre-cat O2 sensor, take it for a drive. See if it is any better. (on yours, the pre-cat O2 actually screws into the front of the cat... right where the two exhaust pipes come together. Might be as simple as a bad sensor.

Be sure to read the plenum thread, stickied at the top of this forum. Plenum issues can lead to fouled O2 sensors, clogged cats, etc.

 

Unless you have fixed the plenum, the plenum needs fixing (these trucks are known for it)... start there, as that would account for your issues.

 

I was getting misfires on 2,4,6 and sometimes 1 and 3 last fall. Didn't set a CEL but could see on scan tool. Caused a shaky, vibration at idle only. I didn't think it was the plenum leaking until recently. Oil use has increased to 1 qt 1600 miles. My sparkplugs are white as rice, (running lean) vacuum leak from extra air from crankcase. What I'm saying is you got what I got, only worse. I think. I got my aluminum plate and gaskets and plenum is getting done, the sooner the better.
It sucks but start there. No pun.

 

yea that bad plenum gasket can cause a lot of misfire issues do to a lean condition,also when i did my gasket i found out i had a cam lobe wore down to nothing as well,definatly inspect that when the intake comes off...

 

Thank you guys for the Responses im going to try the o2 sensor unplug today and also just bite the bullet and order the hughs kit ill keep everyone posted

 

Any luck with the problem? I am having idle issues with my 1993 5.2L. I have the same popping, but did the key dance and did not have any codes come up. Mine runs fine, the idle is just low and i have a popping under heavy acceleration.

 

Sub'd for results. my truck is running terrible, shaking in O/D and almost no power. no popping but running rich I can smell the gas. (have jegs y-pipe and hopefully soon to have the plenum done). replaced the O2s when i put the jegs in, no codes either.

 

He hasn't been around since early April. Don't expect anything to come of this thread.
