Engine Performance problem
1990 Toyota 4Runner 6 cyl Two Wheel Drive Automatic 177000 miles
I have a new automotive nightmare I desperately need some assistance with. I just bought a 1990 4-runner 2wheel dr 3.0 3VZE as a project vehicle/work truck. The truck was running a little rough but not that bad and decided she needed some tune up attention. I replaced the plugs, wires, distributer cap & rotor. Now the motor has no power under load! It Idles good but goes from 0 to 60 in about 5 miles sputtering all the way. It gets worse as it warms up or if the gas pedal is requesting more. I've checked the timing all the vacume/intake hoses that I can find and all seems to be in order. I am beside myself! The funny thing is that I was removing all the old components and wondering how the truck was even running at all, & now with all new stuff it's running worse than ever? I did notice that the NGK-G power plugs that I used were gapped about 4 thousandths (.035)over the gap of.031 that my repair manual calls for. I did not think it would hurt with a small increase of the gap so I left it be, was I wrong? :-(
PLEASE HELP :-)
have the same problem?
