- 1994 XLT 4x4
I have a 94 XLT 4x4 4-door with a bone stock 4.0, approximately 180k on it.
Yesterday while on 45 miles trip to buy some tires I found for sale on Craigslist, the blower motor completely stopped working.....since it was relatively quiet without the A/C goind full blast, I heard something I apparently hadn't noticed before.
At full throttle either on level ground or going up hill there's a rapid ticking noise coming from the engine. Can't pinpoint it from inside the cab, but it sounds like it's from the top end. I replaced the plugs along with some other parts (MAF sensor, shocks, A/C compressor) about 2 months ago as part of the "Weasel Summer Maintenance" package. I used NGK platinum plugs (http://www.autozone.com/autozone/parts/Ngk-Gp-Platinum-Spark-Plug/1994-Ford-Explorer-4WD/_/N-j56q5Z8gctd?counter=13&itemIdentifier=441310_0_0_), ran a can of Seafoam through the gas tank and also directly into the engine via the vacuum line method, changed the oil using a Motorcraft filter and 5w-30 dino oil, and put in a 198° thermostat at the same time I did the plugs.
One thing of note is the octane rating for fuel - due to the altitude here (5000+), we have 86, 88, & 91 octane with 10% ethanol. I normally run the 86 octane from the same one or two stations, though I have used fuel from other stations as well and have tried the 88 octane on occasion as well. Changing stations or octane didn't really seem to make a difference.
The thing that's driving me nuts is that it's only at 100% wide open throttle...if I back off just a bit it'll quit ticking.
