5.0 EFI idle issues?
#1
ok now that ive been running the bronco since Thurs 12th...ive notice the motor is running a touch rich...no smoke tho. also when im trail riding, no issues. but, when i drive a short or long distance above a certain rpm...when i come to a stop(ie. traffic light,stop sign,etc.) it takes a good 20-30secs. before it will come back to the set idle. this is kinda aggrivating since it makes down shifting a pain. can anyone give me some thoughts on this.

motor is a 91 mustang 5.0 HO, a9l computer,rjm harness,egr delete, new o2 sensors,new coil,wires,plugs. thanks,Chuck
