I put a 91 roadmaster in a chevy truck and now it smokes real bad then it clears up i put a map sensor on it already what else could it be?

since you've replaced the map sensor I'll assume you're dealing with black smoke. a bad coolant and/or intake air temperature sensor could create black smoke, also a bad injector could do it, especially if it's monopoint injection.

I just bought a 95 buick roadmaster limited dule exhaust with 137k for 2300 did I get a good deal

I would say that any car in this year range and milage for $2300.00 would be a good deal as long as the engine and transmission are in good working order.

The cruise on my 93 roadmaster quit ? the cruise light comes on but wont **** the gas peddle down to engage. times it will pick up other times it wont. the fuses are good and the middle brake light works....

Make sure the brake pedal is retracting all the way back to its full up position. Do this by placing your toe under the brake pedal and gently raising it all the way up. Or it could be a combination of brake pedal not rising completely and the brake light switch not adjusted correctly linkage can be adjusted too tight thus preventing the brake pedal from rising completely, also check under the hood if that model uses the vacuum diaphram is working correctly ,,

91 buick roadmaster lacks power/ major backfire seen in cat

if the catalytic convertor was cherry hot or even close, it is time to get it replaced. what happens is after a while of use it can plug up with carbon and not allow for sufficient exhaust flow causing an extreme loss of power and potential for severe engine damage and possble fire hazard. take it to a trusted muffler shop quick and get their opinion also. this shouldnt cost more then $200 high. cheers

check for a fuse,i believe its by the drivers side door in the dash,then check if there is vacumm going to the cruise control,check to make sure the brake light isnt staying on,check to see if the linkage is still hooked up,and try wiggling the on\off switch back and forth(slide switch) could be a bad switch which the turn signal switch is on the same setup,or the cruise unit under the hood.
