I have an 89 Formula 350 that I am having idle problems with. It kicks up the SES light every morning and has the EGR code in the system. We replaced the valve and it didn't solve the problem. It hunts for idle at stop lights surging up and down. It has died in the past. It seems to run worse when it gets warmer out side. If I broke it out of storage now it would run good till it got hot outside. We have tried cap, rotor, plugs, plug wires, TPS, Baro sensor, O2 sensor, ECM, and I even took it to a dealership. They told me that I had 6 bad fuel injectors and that it would be $1500 for new ones. I don't think that the car would even run with 6 bad injectors. I am getting pretty frustrated. Fortunatly the car only does it at idle, if you give it gas it is fine. I don't even to have any lost HP. If anyone has any suggestions it would be great. I don't know what I would do having my car idle right again! Thanks!
