i have an '02 capo that has been in a garage for about 18 months. i am having trouble with it reving around 3Krpm and it is also backfiring.
I have updated the map and it didnt help. i checked the airfilter and it has some "blow back" on one side. the throttle body is clean on one side and a little dirty on the other (from the blow back obviously).
can anyone give me an idea on things to try?
could it be throttle body alignment?
does the blow back mean that something is really wrong, or is alittle ok?
any help would be appreciated.
