Rules for emissions

CEL - check your cel befor you go. if your car is obd1 there is less chance of an issue but the code can no be read by the code scanner, you must turn on the CEL flash sequence under the glove box. 96+ cars have to respond to the code reader (you can not have any emissions related codes or it will fail), this means no obd2 jdm ecus or obd1 ecus(jdm obd2 are obd1 ecus in an obd2 case) JDM motors are good, just have a cat and properly running. if you have a 95 or below motor in your 96+ car, it will more than likely fail.
