Buying cheap 99 explorer for cheap and few things I'm worried about. First off rear two doors are stuck which shouldn't be hard just a pain. Second it there's no smoke coming from exhaust thank god but needs a tune up. What is involved in tune up for it? Coolant flush Oil change Air filter Spark plugs Cool pack Clean tb.

How much blow-by is coming from open oil fill cap when motor is idling? Consider cleaning the MAF with MAF only cleaner, be sure let air dry 15 minutes before starting engine, also cleaning the IAC. Do the spark plug wires need changing?
You can see and feel pressure coming out of the open oil fill cap. This means more than usual compression is coming past the rings and indicates high wear in one or more of the cylinders. Another indication of excessive wear or broken oil rings is oiled up spark plugs weather it be a single plug, several or all.
Truck has some hesitation when over 2k rpm when accelerating. Alison I need to clean iac bc idle surfers 900-1200rpm Sent from my iPhone using Tapatalk
I'm assuming it's a 4.0. I know they need timing chains done around the 150k mark so keep that in mind. Cleaning the Maf is a must as well as replacing the intake gaskets, that will cause some hesitation too. Sent from my iPhone using Tapatalk
