Hi All, I've had my 97 Hilux for couple of weeks now and have noticed it losing power very intermitently couple times each trip. Usually while cruising, however it has done it once while accelerating.
Example:
Driving on freeway at approx 90km/hr 2000+ rpm, sudden cut of power for half a second, then back to normal. Sometimes has happened for a couple seconds as if the fuel is being cut out... Its usually while cruising, however it has happend once while accelerating.. I have been putting Shell V Power in it.. I thought it could be a bad batch of fuel and refueled the other day on 95 octane, problem still there...
I would say the frequency of it has increased over the last few weeks. Hardly noticed it when i first had it. Sometimes you can drive a 20min trip without it happening at all. I would say its very intermittent.
I have changed plugs and also put in new leads which have not helped it at all.
Also i cleaned the MAF with contact cleaner, I'm wondering if that caused any damage? I have also changed the air filter which was completely clogged up
Car has extractors i believe, and you get a resonance in the exhaust around 2200rpm.. wonder if that has anything to do with it?
Could the injectors be getting cleaned by V-Power fuel... i know its far fetched based on the V-power gimick but im just trying to consider all things...
I've read a few things on this, i.e. cam position sensor, fuel filter etc.. Just wondering what my next troubleshooting step would be or any tests that i can do to rule things out?
cheers
