Engine misfiring badly/not driveable
Today, when I tried to start it, it gave a small cough/misfire & quit. It would not re start, (turns over good) , unless I floor the gas pedal. Engine panel showed " low coolant" and "service soon". When I got it started agian,threw out some blue and mostly black smelly smoke, but still misfiring, running real rough, will not idle below 2000 RPM. If you let it go to idle, and try to give it a bit of gas it quits. I don't think I could drive it to the shop.
Year: 94 6 speed, 75,000 miles
Other info that may or may not be related:
-the coolant reserve tank is empty
-I live in Canada, the car stored inside for the winter, have put about 400 miles on it since taking it out on the road Apr 1.It has been running close to perfect up until now.
-I had the coolant tested last fall, it it tested fine, should not have frozen based on the report I got from my mechanic.
-Someone has suggested I may have blown a fuse on half the injectors?? How do you find the fusebox on this year?
I'd appreciate any ideas on what to look for before I call the flatbed!!
Thanks, Dan

Check your oil to be sure it isn't full of coolant and fill the cooling system. Then start trouble shooting the codes that triggered the Service Engine Soon light. Once you have the known problems fixed, we can attack whatever symptoms remain.
RACE ON!!!

but it sounds like you may have sucked a head gasket or possibly an intake. no coolant and smoke are indicators of coolant in the chamber.
you can also check plugs to see if they are wet or fouled out?

Thanks guys, I agree, it doesn't look good, my first thought was antifreeze, the smell of the smoke was too strong to be just flooding.
I got it running long enough to get it into the shop, will keep you posted.

The problem was a bad temperature sensor. It was reading 30 below, so the fans would not come on, overheated, boiled out the coolant .I am hoping the engine will be OK, it must have got pretty hot. No collant in the oil.Funny thing is it never threw a hot engine signal, and I never noticed the temp indicator needle going high? Just when you need an idiot light, where is it??
Anyways, it running good for now.
