I have a 95 V6 Ford Windstar Van 3.8
Bought Nov. 99 Mileage at that time was 62558 km
Dec. 99 replaced Thermostat
Mar.2001 checked many times for coolant leak could not find any
In June of 2001 we had a antifreeze leek that Ford could not find it was leaking on our driveway
also vehicle speed slower than driving speed
to make a long story short and after countless times in going to the garage they took it for a drive came back parked it and the motor blew
cause Catalytic Converter plugged heat build up.

Dec. 2004 replaced flex pipe between catalytic converter and muffler there are 2 cats. on this van to pass the emissions test.
What is happening now
engine light was on... it took along time to heat up... loosing coolant no leek could be found ...poor gas mileage... Transmission sticks at 2000 until you hit 70 then drops to 1500 ... ABS light comes on and stays on now once it heats up... have no high beam light unless I hold them on... very little head lights ... right front turn signal does not work flashes fast inside the van ... Rear window wiper motor burnt out ...and the outer edges of the tachometer and engine coolant temperature gauge does not light up... and when the van does heat up it is so hot that you had to roll down the windows it was burning hot . Sat. morning
On Sat. we replaced the thermostat
Now engine light is out but yesterday could smell something burning now to day a bad odor like rotten eggs and I mean bad and every thing else is still the same .
Can any one please help me to find out what is wrong can't afford to take it to a garage.
Can I still drive it or am I going to do more damage. I use it at 5am every morning for about 2 hours of continual driving
It is now Thursday and it is still smelling like rotten eggs and I am afraid of driving it because I don't know if I am doing any more damage.
Please can someone help me.
