 Subject: how to fix a really high idle??
IP: Logged
Message:
i have an 87 with a 3.9 v6 4wd auto.
my question is, i just replaced my exhaust from the motor back. it is 2.5" pipe the whole way back from the Y pipe off the motor, with a catco hiflow cat and a flowmaster 40 series splitting off into 2 after the muffler (also 2.5" pipe). it idles really high now at im gonna say around 2200 rpm (i dont have a tach so i cant tell exactly), but its really high.
i was wondering if there was an easy to fix this? would just adjusting the carb do the trick?
oh, also i have hotter plugs (ill see what #, and they are gapped at .035"),heavier wires, an accel coil and a 14x3" K&N filter.
i had 2.5" pipe from the stock (gutted) cat back to the flowmaster with 2.25" tail pipes before. also i didnt have the new coil, plugs or wires and it idled fine.
any suggestions?
thanks
