Greatest man alive
Hello, Some may know I just bought a 98 ford explorer sport 4x4. Its and auto with an 4.0L SOHC engine that has 125K miles on it. When I got it, it was idling really rough, from the stock tach seemed to be close to 600 rpms. I pulled codes and got
P0304 (Cyl 4 Misfire Detected)
P0305 (Cyl 5 Misfire Detected)
P0171 (System Too Lean-Bank 1)
Well I cleaned the MAF, Cleaned the IAC, and put in new spark plugs and wires. I Then erased the codes and and took it for a drive about 5 miles down the road. It was still idling rough, But not as bad and I think I have the timing chain death rattle that I have been reading about. But the Check Engine like did not come on till I got back home and parked it while idling. The new codes are the same as above plus
P0300(Random/Multiple Cylinder Misfire)
What Else should I try to do to get this engine to idle right. I runs fine on the highway and Has plenty of pick up and go. Its just the idle pretty much shakes the whole Vehicle. Can anybody pin point some things I should look at instead to just tossing money at it, Would running seafoam through it help any?
Thanks,
John
