I just did a tuneup plugs,wires.coil,cap,rotor,control moduel, even changed out dist. It runs ok on the freeway but misses when i'm taking off. It doesn't seem to run as good as it did before tuneup gas mileage is 21 on hwy that to seems more. Idles good when cold but so as warm taking off at lights it misses until I get over 40

sounds like an injector. you have done the basics now it time to get some help as you need to identify the injector, test it and have it replaced.

take it to a shop to verify.

I thought it was that i put some cleaner in it and that helped but it still is not right thank you again .
what company for repairs other then dealer can do a "REAL" injector cleaning? I have been told that most places charge $70 to upwards of $120 for that service and you can get same results just using $10 bottle of lucas injector cleaner yourself.
the cost is about 79. this cleaning is not an additive that has little effect on the cleaning process, it is a direct injection into the injector rail and injector that cleans the carbon from the pindle. takes about an hour to perform and is well worth it.
