Lately whenever I idle at lights my Service Engine lite goes on, one shop said engine miss fired once but nothing else, another shop said fuel injector & intake gasket leaks spend $2100 to fix, also gets bad gas mileage. Vehicle has 97,0000 miles, is it time to put to pasture? Another post suggested EGR valve could be a problem - spendy shop said egr was not a problem. should I keep getting opinions?
Thanks
Jim
