Hello all!
I have a 91 4-runner that I’ve owned for ten years. It’s a V6 with 4-wheel drive, manual trans. For the past six months or so it has developed some nasty habits. I’m not sure if these items are related, but I have a hunch they are.
First and worst: it smells like gas in the cab, bad! Especially when it rains.
Second: after running for a while, when stopped at a stop light in neutral, the idle rpm goes up and down from 1000 to 1500 RPM like a pendulum. Up then down then up then….you get the idea!
Third: it’s hard to start in the mornings. It takes about 5-6 seconds with the starter engaged, and a few pumps of the pedal.
I’ve had it to a mechanics, and they said it was a cracked injector and replaced it but the problems were still there. Then they said it was the injector o-rings (or something like that) and replaced those but to no avail. I’ve taken it back three times, and they just keep replacing the o-rings saying this time it will work! I don’t think they are using official Toyota o-rings, so this may make a difference.
I spent $750+ on this repair and it looks like money down the drain! Can anyone give me some ideas on what could be wrong? Thanks for the help!
