Any of you heard of this?
I've had rough throttle issues for a while, so I worked it out to a plugged carbon canister. Stomping on the gas, especially after filling up usually resulted in a coughing and spitting engine. Unhooked to vent hose from the canister coming up from the gas tank and problem is solved.
After two days of no problems, I have this and it has me stumped big time.
Driving home at 100 kms/hour, I filled up. It starts raining. When I hit 3500 rpm in 5th gear, the engine misfires repeatedly. If I let go of the throttle to below 3500, its fine. Does this consistently. It acts as if there's a rev limiter.
So I played around. dropped it into fourth, and I could do 4500 rpm, but then misfires. It seemed that if I hit 60 kms/h, it misfires.
I should ad that before this issue started I heard a loud click.
Any idea?
I can't even begin to wrap my head around this one...
