Cold it be a Vacuum line?
So over the last couple of weeks my RED 90 has been running worse and worse ..rough idle etc.
I also noticed that it has not been shifting right it has been slow and it clunks a bit.
I did have a problem with the injectors but after 4 fill ups and injector cleaner it seems to be fine now with no tell tale speedometer bounce.
I made an appointment with my mechanic friend to replace the plugs and tune it up.
SO last night I went out to pick up a movie and I turned the corner at the light and It took the longest time to up-shift and acceleration was pretty bad then suddenly it really started to run bad and stalled at the next light.
It stalled 5 more times ..4 in the Wall-Greens parking lot. I took the back way home ..slowly and steadily running rough but steady.
So I'm thinking what would affect the engine and the transmission? Vacuum Line ?

Re: Cold it be a Vacuum line?
No, a vacuum leak will cause a high idle on a fuel injected engine. I would remove one plug wire at a time to isolate the affected cylinder. You most likely have a bad wire or injector.
