Hello. I recently had my EGR valve solenoid replaced and I am still experiencing problems with my 1995 nissan maxima. The car has 365,000 miles on it and it has had limited problems in the past. It would hardly run (stalling, sputtering, would not take the gas) untill I had the solenoid valve replaced. Now It runs fine as long as I am moving down the road. However, at a stop light or stop sign when the car is in drive, it acts like it does not want to idle. I do believe that carbon build up is causing the problem (that is what Nissan told me as well) but I am not familier with the EGR system. I also had it diagnosed at advanced auto and it came back egr flow malfunction. I have read some of the other posts and they say to clean out a certain metal tube on the intake. My question being, where is this tube located and what does it look like? I am not exactley sure what to look for. One guy told me to disconnect the straight pipe I have before the cat converter and blow it out down the road. Not sure what to do. Any other suggestions would be greatley appreciated. Also is this why I am only getting 24 miles per gallon of gas?
Thanks in advance,
