'05 XLT V6, ~85k. Truck was suffering from P0430 (Catalyst system efficiency below threshold (Bank 2)) and moderately uneven idle for few years, but yesterday -- peaceful local driving, stopped at intersection, when started moving (no noticeable "pop" or "clang" or whatever) -- engine shaking...

94 Explorer Sport, 4.0, manual trans - Driving short trips, everything works fine - acceleration, smooth running - after about 10 miles of highway driving at ~ 1500 RPM, it starts bogging down on hills and if I try to accelerate, it acts as if it's running out of gas. If I back off the...

So I have a 96 explorer xlt 4.0 ohv and can't seem to figure out what is wrong with this truck. You can be driving along for about 20 minutes and when it gets warm it's like the truck doesn't advance in timing; won't go past 20mph uphill. I have replaced fuel pump, fuel filter, fuel injectors...

I'm having an issue with the engine fan coming on under light load (not on constantly), making a roaring sound. When this happens, I feel the truck loses power. It will keep it's speed, but accelarations are weak. The transmission will down shift, the revs go up, but the acceleration does not...

After years of my car sounding like a freekn harrier, and seeming almost adiabatic in its performance (literally could drive an hour at highway speeds, park, and safely place my hand on Air Intake Manifold ), I've decided to address the issue. It had never occurred to me that my lower than...

My son was driving, battery and check engine lights all came on, lost power. He limped it to my mechanic who replaced the alternator. Then runs fine for a short time then same thing happens. He checks all the codes, the system are all ok. Resets, then drives fine, for a bit, then starts all...

Hello All - First time poster. I recently acquired a 1993 Explorer XL, 4.0L OHV, 5-speed manual transmission. It's well-used, LOL, but overall seems to be in reasonable shape for it's age. But, it has a problem I can't seem to figure out. Inconsistently (I can't establish a pattern), it will...

Hi guys, this is my first post here as I've run out of hope with this dang truck. It's a 1997 Ford Ranger, 2.3 liter 4 cyl standard. I've been using this truck as a daily driver for over a year now. The other day I jumped into my truck, everything ran fine, ran to the store and came home. The...

so i finally got my truck up and running, but on the test drive there was a loud back fire, driving back home it kept back firing, several times idling at lights and about 5-8 back fires upon accel before i reach 25 mph. i also noticed a huge power loss. checked under the car and theres a large...

My 1991 explorer is posessed i swear! my engine idles rough shaking the whole car and emits black smoke from the tail pipe when i start it that smells horrible and has now painted my curb black. also my volts jump from 10-13 while its warming up and when driving at temperature. when i come to a...

Hello all ~ My wife was driving our 2001 4x4 explorer and she lost all electrical power. Went to the car and jumped it for 10 minutes - car started up but then lost power after we tried to drive it home after a few 100 yards. Took out the battery and alternator. Battery charged and was OK -...

I'm working on a 2000 awd explorer xlt w/ the 5.0 and 240K miles under its belt. I've noticed that around 3000rpm the engine becomes week and seems sluggish to get to the higher rpms. After 3000 rpm power returns a bit but not what it used to be. I recently replaced the Mass Air Flow...

Got a 91 Explorer from my father. He just rebuilt the Trans. Got it in Feb and ran great. Now when the outside temp get above 75 degrees, and the engine has warmed up, at about 1500rpm the engine 'bucks'. Tach goes from 1500-2000 rpm to 0 rpm and then back up. Feels like I riding one of...
