'91 300ce Stalls When Engine Warms Up
HELP!
My wife's 1991 300CE (135K, exc. condition) runs perfect with one exception...when the engine is fully warmed up she stalls (doesn't die, but almost) and runs very rough until about 10-15 mph...then runs fine! I have changed the wires and put in BOSCH Platinum Plus 4 plugs, run Techron cleaner through it, and it was fine for about 2 weeks. Now its the same old story. Runs great until I stop. It idles fine until I press down on gas to go and then it starts to die out, no power, etc. until speed gets up over 15MPH...then fine again. Also, I haven't been able to get HC levels low enough to pass emissions test: Need to register 1.2 and lowest I can get is 1.8. (It had been up to 2.8 before I started working on it) Any suggestions? Many thanks to all!
