Is it okay to clean EGR with carb cleaner?

Replying to: grabber7 (Apr 07, 2009 7:15 am) I am sure you did not disconnect the battery properly. When you did this You erased all the E.E.R.O.M Electrically erasable read only memory. I would not be surprised If the computer needs to be "reflashed" or reprogramed or even worse you might have done physical damage to the computer. Maybe if your lucky the PCM Power Train Control Module will re learn Its programed instructions. How do you know the battery was to small? Make sure you did not put a larger battery then needed compare the old and new battery. Hopefully you put O.E Orgnial equipment spark plugs in the car. There is a lot more to batteries, spark plugs and even air filters Nowadays. Every thing is tied into each other and the computer. I would suggest taking this to a shop. Hopefully this helped.
