ok sooo
im sure its the passenger side because i unplug the 1,3.5 spk wires and it runs smooth.

started out only missing sometimes now its all the time


i have done:
comp test 120psi all around <i know its low but its there all that low>
and i have checked spark and cam timing
no MIL
new
cap, rotor, wires, plugs,



i need help bad i have already pulled the valve covers off and im wondering whether to pull the heads. i do NOT want to have to pull the head after i put it all back togather

why did you have the head off the first time?

drkblu4runner

probable helps that you know its a 93 4runner 3vze mt 200,000 mi
.


how easy would it be to put a 22re or 3,4 in there?

drkblu4runner

heads are on as of now i pulled the valve covers to fix oil leak and look around

i had the same thing happening with my '99 dodge. i know it's not a yoter, but i thought i'd throw out a suggestion. i checked compression, everything checked out ok, replaced everything excepet the distributor itself with the ignition. replaced all the spark plugs three times within a hundred miles thinking they were fouling out. nope, still had cyl 1,3,8 misfiring. it's automatic and when i went up an hill or pushed the gas pedal anymore than just normal driving, my heater vents on the dash would switch to the defrost. i did some checkin, i had lots of oil in my intake manifold. so i replace the intake and plennum gaskets and the thing runs like a charm and no more misfire. no more codes. hope this helps a little, good luck gettin it fixed

Was the miss there before you pulled the valve covers? If not check the injector wiring harness on the side with the miss and make sure it's not pinched under the valve cover.

drkblu4runner

ya im prayinng that this fixes it. i had a 2000 durango with a magnum in it and those things crack between the valves after 100k
ill let you know how it goes thanks for the help

drkblu4runner

it was missing before i got touched it so the wires were not being pinches could it be coil or injectors or dis

drkblu4runner

ok so im stumped

i put it all back together and the miss is still there BUT i went to unplug the TPS and the miss STOOPED and there is no mill. i know this should be a nobrainer to someone that knows the 3vze. so if your out there please HELP

drkblu4runner

i got a new tps and adjusted it and the miss is still there. does any one have a wiring diagram that shows what els is interupted when it is unpluged so i can chase the prob down?

CappyKD

Vacum leak. Or throttle body service?

drkblu4runner

im not sure what your asking, but there shoudnt be a vac leak


the idl does jump up when i unplug the tps tho

drkblu4runner

any one have any ideas

yotaman85

injector.

drkblu4runner

tested all injectors and unplugging tps wouldnt effect a dirty injector i dont think at least. im guessing its the distributor coil or maybe vafm

drkblu4runner

still cant find it im about to bring it ti dealer

drkblu4runner

brought it to the toyota dealer today and they charged me 130 to tell me they have no clue what it is and they want 500 to look more.

drkblu4runner

please help they messed it up it will now not rev past 3g i dont know what they did they may have messed with the ps and timing but i tried to set the timing and it is correct but when i move the distributor to the middle (were i had it set b4} it runs better

they said it "may" have a burnt #5 valve but i have done 3 comp test and they are all about 150psi


also still have that miss i ordered a coil/igni \, any sugestions would be greatly appreciated!!!!!!

ospartier

Hey man, have you figured this out yet, because I am having the same exact problem

drkblu4runner

nope im going to try adjusting the tps and see how that goes. does any one have any good howtos on that
