I have a 1986 Camaro IROC with 5.0 liter tuned port injection V8 engine. Recently I drove the car about 4 miles or less after not driving the car for several months. There was a great deal of misfiring apparently from clogged fuel injectors. The Service Engine Soon light came on briefly. After adding
2 bottles each of 2 different kinds of fuel injector cleaner and driving about 2 miles the problem was solved. I am concerned, however, that the catalytic converter may have melted or have its efficiency reduced. Unfortunately, I do not have any baseline data from an emissions analyzer. I want to have a free flowing exhaust system and also an effective emission control system. Any thoughts on this would be appreciated.
