So, I left out thrus. morn on my Way to Alabama for a Youth Rally, before i even got to where i was meeting up with my Pastor my SES started flashing.. so of course i got off the interstate, and scanned the codes.. it was 305 - Cyl 5 Misfire Detected (it started doing it in Cruise Control going up a hill when it dropped back down a gear) so, i started messing with cyl 5 spark-plug wire.. made sure it had a good connection etc.. - it did.. so i cleared the code, and on i went with No cruise.. - met up with my Pastor and everyone else who was going, and started on the road - shortly after, SES just came on.. no flashing.. - waited about 100 or so miles till everyone pulled into a rest-stop - it was 306 - Cyl. 6 Misfire.. well, this time all i had time to do was clear the code - rest of the trip was OK i just didn't get on it and i averaged about 75mph the whole way.. - got into Ala. Got under the hood, got all the junk out of my way, and i started checkin the wires - Cyl 1 was un-plugged about half way.. well, of course i plugged this back in - everything else seemed fine - it Ran GREAT! while in Ala. - Coming home.. once we started on the mountains it did a Flashing SES.. didn't stop just slowed down to where it would stop misfiring.. and this one was 300 - Random Multiple Cyl Misfire... - ok cleared the code, kept going.. got back into NC, SES light came on and stayed on no flash.. - got home After a CRAZY! night of driving, (alot of problems not with my vehicle but with wrecks, and etc long story) - No sleep, went to Church, came home after checked the SES light - and it was 305 again
Well... I know it needs new plugs... they don't have alot of miles on them, but they are fairly old.. and i have never replaced the Coil.. so i'm gonna do that as well - how about the Dist. Gear? is that an easy one? - Also should i just go back to a factory coil? - Also i have a significant exhaust leak before Cat.. drivers side.. dunno if this helps matters out - going to have this fixed as well - And i think thats all of my questions... - Sorry, i'm extremely tired, and i'm leaving right after church tonight to go be a counselor for a Youth Camp so... it may be awhile before i get back to this topic..
TIA!
