this problem dates back till last year. the car was out of commission for the last 3 months, as i was installing a new tranny.
the car hestiates/bucks/misfires at rpm's under 3000. im using 87 oct fuel, changed teh spark plugs 5 times usually helped but this last time it didnt. new spark plugs are 4 days old and i made sure not to over tighten them they are at the right torque specs. the wires have 4 months on them. as well as the ingition coil.
from reading the website on a similar problem, some one suggested carb cleaner and spray around the vaccuum lines to see if the car chokes. i did this yesterday, and the car didnt choke.
at high rpm the car seems to run and pull just fine. or it just cover ups the misfire. but the car seems to be running high and revs up pretty quicky after 3k. but its takes a long tiem for it to get to 3k.
so now the question is what can this thing be. its not the fuel filter or the fuel pump as the car would have a bad tiem at high rpm as well as low.
thank you very much, i welcome all responses as long as they dont hijack topic.
