so i had my plugs changed from copper 2254 autolites to app764's...they worked great in the summer, no detonation, no pinging....did i mention they were gapped to .050?
well last night was a little colder than normal, after i got off work around 10pm i started the car and was driving home, but it was a little rough, like a misfire when it idled, the vac guage was at 12 at idle...then it warmed up a few blocks later, and the trouble was gone the vac went up to 18... i also have been running considerable amounts of additive and water instead of a 50/50 mix of coolant water.
so does this mean its time to change the %?
or time to change the plugs?
also i was low on gas, but i filled up right before i got to work...maybe i got some crap from the bottom of the tank into the fuel filter or injectors...the fuel filter only has 3k miles on it. the plugs only have 2k miles. also bought new plug wires (motorcraft)
well any ideas?
i only run 91 thats the best octane rating i can get from the regular gas stations in california.
also i just switched to 15-50 mobil one, about 2 months ago. didnt drive bad, only idled like crap, but then again i didnt go over 2500 rpms. unti lit warmed up.
