My 1994 Ford Thunderbird now smokes when I start it - no noises in the engine, but smokes like crazy. Check engine light is one now?

check your mass airflow sensor,( located on the air intake line,probably close to where it hooks onto the front of the car on driver side ,should be a square box with wires plugged into it) take intake hose off and spray filiment wire with brake cleaner to clean,do not touch wire with tools or hands it will break very easily ,let dry and replace hose and see if that helps.

Sounds like head gasket needs replaced or worse one of the heads is cracked leaking antifreeze into cylinder burning out the exhaust, would advise not to continue running as you can lock up the engine if antifreeze is leaking into the engine oil. It will seize the bearings blowing your engine.

Sounds like a weak battery

try to disconnect battery for five min and reconnect to reset computer. berrydalewolf

CHECK ENGINE COMPRESSION.SOUND LIKE YOU HAVE WORN ENGINE VALVES AND PISTON RINGS AND VALVE SEALS IF ENGINE SMOKING BLUE.IF YOU ARE GETTING HEAVY WHITE SMOKE.YOU HAVE A BLOWN HEAD GASKET.WHEN DOING COMPRESSION TEST IF COMPRESSION READINGS 90 - 80 WORN RINGS 60 - 40 BLOWED HEAD GASKET.

there is no reset switch,either take it to a big name auto parts store and have them use a scanner to give you the codes and turn off the light,or just disconnect battery for 3min and the light should go out. the first suggestion is the better, this way you will know what turned the light on in the first place, get back to me if you need more help, please rate my fix

check the connections at the battery, make shure there is no corrosion,also check that the ground wire from the bat to the engine is in good. if you have an ohm meter check the wires themselves,should show no resistance, please rate my fix,check back if you need more help Ray

had same problem on my 94 v8 bird try replacing the mass air sensor fixed the same issues on mine
