Okay, the car has gottne a tune up a month ago and run fine. New plugs, wires, dist cap and rotor, oil change, air filter, and cleaned the MAF sensor with a special cleaner spray. So today I drive to my 1st service call fine, then on my way to my second the car starts decelerating and loosing power. I limp it home 5 miles and it can't go above 2k RPM. Put it in nuetral and won't rev above 2k, just sputers. I turn the car off, then right back on and it revs fine. No engine codes, but when I open the hood steam is spewing out of the overflow coolant bottle. I am waiting for the radiator to cool down a bit now so I can check the level, and add if neccessary. Any ideas, I cannot find my Haynes manual anywhere. No engine codes or CELs have appeared. Need help asap. Thanks! ! ! ! ! ! ! !

First ideas that I figure out are either blown head gasket which makes pressure to cooling sytem or the other one is that engine is overheating and boiling coolant. This can be because of blown head gasket (makes pressure to cooling system and blocks water flow perhaps)

You can try to determine if it's head gasket by warming up your engine so that thermostat opens and water flows all over your system and check your radiator if there are bubles coming out.

Or if no bubles are voming then it also might be jamned thermostat which causes existing water to waporize. Also in this case it's more than propable that your head needs some machining. It could ave been bent when engine overheated.

for now there are pretty many options. but there is something to begin...

Thanks for the response. After letting it cool down, and removing the cap, the radiator was bone dry it seems. The temp gauge never really went too high, maybe 2/3 up, not even in the H zone. I poured in some Redline water wetter and some Bars Radiator stop leak. Seems to be running okay the rest of the day, we'll see how tommorrow goes. Good news is for some reason my A/C works now. No stuttering or lack of acceleration, the temp gauge needle barely made it to the middle, so hopefully the car will last the rest of the month without incident.

hmmm... Normally there has been used green coolant fluid. You said you put red liquid there? If so then I really suggest you to change your coolants because it's possible that those two mixed together will cause engine overheating because it might start two create fome and maybe to boil on totally too low temp. One local taxidriver broke up his engine by mixing these two fluids. Never mix red and green liquid!

And remember that you still have possipibility that your head gasket and head has got some damage. head might be bent because of engine getting too hot. check those bubblues on the radiator cap when thermostat is open and engine running. Hopefully you see bubbles if gasket is blown.
