QuestionHi, I have a Suzuki vitara 1993 JLX. Recently it has been "surging" or "missing" REALLY bad and you can smell fumes whilst driving every now and then. As being a female I am struggling to diagnose what it might be or what to do about it. It gets about 240kms to a tank (roughly) is this normal? I read on a previous question/answer that a similar case was the head gasket - would this be the same with mine?
AnswerIf it's a head gasket, the anti-freeze level is going to constantly drop without any sign of an external leak.
The question is whether it surges all the time, or just while maintaining speed around town. Does it run well when accellerating, and on the highway, especially when accellerating to speed?
It's possible that the TPS (throttle position sensor) is either out of adjustment, or going bad, thereby sending a bogus signal to the "computer", which then can't "decide" whether to deliver fuel, or cut fuel delivery, because it "believes" that the throttle is all the way off, and the vehicle is decellerating. (which may not actually be the case).
I don't have ANY idea of what a Vitara's fuel economy is. While I know and understand electronics, and fuel injection, I have absolutely no hands on experience with Vitara.
I have an '87 Samurai, and once had an '89 Sidekick.
hope some of this helped.
