Hey just bought a 1996 dodge ram v8 5.2l

Exhaust pops when it heats up to running temp and I have cyl #2 misfire code and random misfire code

Changed cap, rotor, plugs, wires, pre 02 sensor.

Still happening, also checked compression and its good. But looking down the TB there's a little oil in there which from what I've read said plenum ?

 

Yep. That's a fairly standard repair on these trucks.

What did your compression test numbers look like?

Welcome to DF!

 

I'll get exact numbers after work, but if i remember correctly highest was 150 and lowest was 120.

 

Previous owner said that it was timing ?

 

If the previous owner claims timing then that sounds like he was messing with the distributor which is not how timing is set. Timing is PCM controlled. Spinning distributor messes with what's called "fuel sync" or more simply, when your injectors fire.

 

In his words "I think its timing, but I didn't mess with it cause its hard to get my hand back there to adjust" lol

 

Sounds like he tried to lol

 

I agree, if it was your truck what would you do next ?

 

Personally I'd go through the easy things first: pull and inspect the plug, check the pn of the plug, check wire routing, look at cap and rotor for wear arching and cracks. From there I'd go through the manual fuel sync adjustment procedure or hook up to a snap-on mt2500 or DRBIII to check fuel sync if you can get your hands on one.

 

Maybe I'll start with the fuel sync, because I did plugs, cap, rotor, and wires. All new and confirmed firing order
