ok where to start....
i have a 91 explorer eb version 4 l v6
here are my problems
my spark plugs get fouled shortly after i replace them, some of them have what looks like caked on oil with what looks like little pieces of black stuff on them...and the plug thats farthest back on the passenger side, the center part thats normaly supposed to be white, looks like it expanded and kinda exploded
rpms
when i got the truck years ago, the idle rpms were around 500, now they are always at 1000 give or take...also when i drive on the freeway at 65mph the rpms are around 3k to 3.5k, i've read alittle on the subject and seen many people say something about ajusting the bands and replacing the filter on the tranny, no idea how to do that, would be greatfull if someone would point me to a thread telling me how to do that....
voltage
my battery is fairly new, nice diehard from sears, my alt is fairly recent maybe a few years old, anyways, when i put her in reverse, voltage goes way down, as well as rpms, the meter used to stay near 18 volts, now it just hovers in the middle, and when i turn my lights on it lowers and the engine makes a weird wobbleing noise and i can see the lights flickering ever so lightly, i dont know much about wiring to see if something is messed up or not
extreemly low gas milage
i have a 19 gal gas tank, i used to get around 300 mpg, then it went down to 250....now its down to around 160mpg and i dont know wtf to do about it
a/c
ok, last year my ac was fine, this year however, when i turn it on, it cycles every like 10 or 20 seconds, and when it does my truck ends up turning off on me, you can hear it cycle with the hood up, dont know if that is normal or not
coolent
ok im having to fill my radiator every 5 days or so, it tells me when it needs filling when i see my temp go up alittle bit, i dont have a presure testing kit for it or i would have checked it out
i do not know how to find out if my heads are messed up or the head gaskets are going or not, if someone could tell me how to easly and cheaply find this out that would be great, as far as i can tell, there is no oil and water mixing
im very good with doing stuff myself and really cant afford to take it into the shop to have them tell me whats wrong
i have a compression tester, but i have NO idea what so ever how to use it and do it without hurting myself or my truck, so if someone could point me to a thread on how to do it great
also would love to know how to tell if my injectors are leaking not working right or whatever, also, how many do i have?
is there something i can pour into the engine that will help at all?
also if someone is around the fresno ca area and would like to help i would be VERY greatfull
lets see, also, recent parts, radiator i think a few years ago, water pump last year due to it vapor locking on me in the mountians, as well as fan clutch, the alt is a few years old, battery is a few months old, the IAC is a few years old, i do clean it often, also the MAF gets a good cleaning every so often, and the spark plug wires are a few years old, i normaly get Bosch-Platinum 4's but i plan on getting the old auto lite gapable kind
thats it for now thanks in advance for the help
