I own a 1995 Jeep Wrangler YJ 4.0L just got it reassembled after repainting I'm having 1 issue it's starting hard I replaced the iac valve no change when it starts firing it only sounds like a few cylinders until it warms up i have to keep my foot on the throttle slightly it sometimes back fires but once it's warm it runs perfectly fine. I don't have a vapor canister in it cause it got lost could that be my issue?
