I'm the guy that asked for help with an intermit miss on my 92 300 ce with mech fuel inject. I took advantage of all of your advise. I changed injector seals and ran a tank full of techtron cleaner. I thought it was improving but today I need the a/c and car barely ran at all. I had to put the pedal to the floor to move off a light. It also is becoming increasingly hard to start. I feel the problem is somewhere in the fuel dist. and I just dont understand enough about it to monkey with it. So in goes the towel. I wonder if the blood bank is open on the 4th of July I fear I may need to sell a few gallons....wish me luck...and thanks again your a good group of folk......Ed
