Thanks for the reply Matcheen and Sevensevices. I'm trying not to resort to a manual choke, but if I must, I will. I'll check into the wiring. I just bought this Jeep a few weeks ago and I'm still trying to figure out what has been modified. I pulled the plugs, they look good and new. The cap and wire look pretty new, i have not taken off the cap to look at the rotor, but I suspect its okay too. When its warm, it runs great. Can it be an air intake issue?
