I recently changed the spark plugs and plug wires in my 2000 5.2L 4x4 Dodge Ram Sport and now I am noticing a destinct power loss, both at high and low rpms. Used champion platinum plugs and MSD Super Conductor wires. Also changed the tranny filter and fluid but I don't think that had anything to do with it.

In addition to the lack of power, mixed driving I was averaging about 340 miles to a tank and now I'm luck to get 280 to a tank.

Any ideas

Thanks

I was reading on here somewhere yesterday, that certain plug wires touching each other can cause that problem.

 

did you do the wire reroute?

 

+1 for the reroute of the wires. TSB 18-48-98.

I know it only says to 1999 model year trucks, but I'd do it anyway.

also...did you gap the plugs correctly to .035 or .35 (cant remember which)?

 

.035

.35 would be a frick'n huge gap...

 

damn, lol.

I know for my year they changed the gap to .040 so you might wanna check to see if they changed that for your year too ( i dont think so) but just throwing it out there. That though, wouldnt make that big of a difference.

 

I'm glad you put that up there I'm getting new plugs ect this week. Got me taylor 8.2's.

 

yea, i was running on like 3 hours of sleep from working literally all day...then going to work again lol. couldn't remember sizes by then lol

 

You should have gone with a regular Champion plug or the Champion truck plugs. There are mixed opinions, but for the most part these motors don't like anything different.
