My 84 245 has become very hard to start when cold. Cranks over fine, but only fires on one cylinder---so hard it almost seems like it's out of time. Seems like it's firing on one cylinder and the others are getting flooded. Obvious smell of gas. Once it starts, it will run very rough until it clears itself, then purrs like a kitten as usual. Subsequent restarts are just fine.

The problem showed up Saturday morning on a trip to northern Minnesota--at first I blamed it on the 20-below temperature,although that had not bothered this car before. Was about 10-below Sunday morning, and we had to resort to dragging the car around behind the truck before it would finally start. This morning, back home in tropical southern Minnesota, it was a fight to get it running at 25 above.

I haven't pulled the plugs yet, but plugs, cap, and rotor are not very old. Cap and rotor looked fine when I looked in there this morning.

Been there?? Ideas??

hi.

I had that problem last year on my 82 240 GLT. I scratched my head for a while, inspected a lot of injection system parts after realizing it was'nt electrical... Turns out it was simply a dirty connector, (not even shure the exact one). I just cleaned every connector I could get my hands on and it fixed the problem. So might I suggest, do that first, it could save you a lot of scratching and the cleaning will only do good! YVES.

Kieth, A bad temperature sensor or temp. sensor contacts will do that sort of thing. It is so hard to take those things out that I prefer to have a new one on hand if I'm removing one to inspect it. Its common for the contacts to get oxidized or loose. That'll make it go way rich. You'll need a 3/4" deep well thats deep all the way down the inside of the socket. Other types hang up on the sensor. Thats another reason to have a new sensor on hand, so you can see if your socket will fit on it. Its located near the flame shield under the intake manifold. Hope this helps. Chris
