ok so i went and got my emissions done and for one i thought i was going to fail since i have only one cat and a flowmaster. however, i passed the test, but i had really high nox, right under failing. it says my combustion temperature is high, how can i bring it down. oh its a 92 explorer...

hey i got a 92 explorer, now the gear tag says its the 3.73 with open diff. i found a 8.8 with limited slip and 4.10's in there. i live in colorado where its very hilly and i drop gears alot and bog some, i did have 31's but went back to stock ize due to the hills and gas. my question is would...

well then i guess i have for sure been proven wrong, sorry for the mess. well anyone have any inpuit how to help the explorer out in the mountains. i know there are gears and crap but im talking more bolt on. its a 2wd so i dont really want to rip gears and crap out and the interstate speed is...

well that is not entirely true only since once the compressor is out you are not running a erxtra pulley. i see what your saying since it free spoins so easily but it also is still more belt to turn with it.

does anyone have a round about idea on how much hp i would gain by removing the ac sytem in a 92 ford explorer. my system is done and i bever use ac as i live in the mountains of colorado. if anything wouldnt it help with uphill driving?

and for the record i dont ever notice any change with octane booster, i mean its a 19 gallon tank to a 12 oz bottle, thats less the .5 ounces to every gallon, if anything it would take 85 octane fuel to 85.001 octane, waste of money.. now if you were to add the 12 ounces to like 5 gallons of...

ok thanks. i installed a new mass airflow sensor about 4 months ago. i also have pulled the heads already twice this year once couse i broke a valve and second to replace the rods,rockers and lifters. the carbon buildup isnt bad in the interior of engine from whjat we saw, it was after a can of...

ok yea ive tried 85 87 89 and 91 grade fuels. had a shop do the fuel sytem clean and i also did one myself, i even ran a bottle of lucus fuel injector cleaner with only about maybe 2-3 gallons of fuel in my tank. same problem still occured. i drove my truck around for a about a day without the...

i got a 92 ford explorer with the ohv im guessing. my problem is during hotter days or driving uphill i get a lot of spark knock( the pennies in a can sound). ive tried everything i can think of, ran diff brands/octanes or fuel, ran a full can of sea foam threw the brake booster vacuum hose, few...

well i did it barly when i bought the truck. everythig i pulled out didnt make it louder it got louder once the truck was in colorado. i was asking about the vacuum lines since i have pulled a few but either bypasssed them or plugged them as well. so im leaniung more towards valve is bad or...

yes, but i till have the maf on there i jusst bought an adapter. \

so i was in the process of buildig a 92 explorer into a trail rig. so i pulled things out of engine bay i didnt need. fender wells, cruise control unit, the box and intake tube from old intake. i have a very loud engiune tap now under the hood, sounds like its coming from left front of motor(if...

i seem to be having a problem with the 92 explorer. when i hit the brakes rather just slightly hitting them or laying on them hard there is this clunk that i feel under my feet. i recently did the radius arm bushings and did the front and rear brake pads. i had almost the same problem before the...

ok its a 91 explorer 2x4. im in colorado from arizona so i got altituide issues. i do have a flowmaster muffler, only one cat. and i made a intake with the flexible tubing and a cone filter. it seems when i hit the gas the motor wines up and is trying to go but not all there. it doent have near...

Yea I did put the clip back on.where would I get a larger throttle body at.and where would I find a chip and a tuner

Well i have a flow master exhaust already. Cold air intake.and why put the chip back I n if the truck runs betterwith out it in.

i just moved to colorado right outside iof denver. i have a 1992 explorer and moved here fro arizona. since i got here the truck runs a little rough, high idle and does not accelrate or run as good as it did in arizona. what are some things i can do to get my performance back. i have already...

im having same issue. i deff have that stupid tick sound from the pushrods but i have the dimes in a beer bottle sound. however ive come across the octane booster and i unplugged it and the motor idled the same, didnt test drive it though. autozone does not sell it, where do i get it. also what...

so ,latley ive noticed my truck makes a odd sound. while im accelerating, no matter if its floored or barly going, it makes this sound like someone has a dime in a beer bottle and its rattling around, sounds just like it. i cant figure it out. is it harmful, anyone know what to do to stop it. it...

im driving a 91 2wd explorer. now what drop would look good with 18's. i was thinking the 3 inch drop beams and blocks in the rear or should i go a differant route.

can you go lower that 2 inches up front without doing a bunch of extra work. ive hear that the ranger i think threw 87-93 is the same up front as the explorer. i drive a 91 explorer 2wd and want to lower it, would like to run 18 inch rims and have it look good so any input would be nice.

ryan, how much is your 1st gen lowered. i have a 91 2wd i want to lower but cant find anything except blocking the rear. how do i go about doing the lowering where cobra wheels would fit nicely. id like a noticable differance from stock if possible

so i recently came across the issue of my locks not working. all the locks will unlock when the unlock is pressed, however when i hit lock, only the front passenger and rear passenger lock, the ftont driver, rear driver and hatch dont lock, they sound like they try but dont have the balls...

i pulled that off. i looked into the dynamat ive found a 100sqf roll for 250, not bad i guess if you look at it the right way. expensive subs and amp, might as well spend a little more to make them sound there best

yea my plate isnt my problem, and i can do with the door handles rattlen, its like the whole rear rattles, dynamat may work i guess it would help more then harm it. doesnt it come in tiny pieces for a hell of a price?
