i have a 94 cadillac deville that ive put alot of money into but on thing i cant seem to figure out is i have no vaccum pressure to control my vent system in the car and most times it starts hard. first the vaccum pressure thing.... everything is connected and nothing is missing... i changed the heater vaccum motor control but no change... i noticed there is a air canister on passenger side wheel well and also another air line going to so type of vaccum pump with alse is interconnected to throttle. id like to get this fixed but i can seem to find a solution then to just replace everything one by one. i also only get heat on the passenger side of car.
no for the hard starts... i usually gotta flick the key a few times along with some gas to get it started... ive changed fuel filter, plugs, wires, distrubuter cap and rotor and no change. used Sea Foam and other carb and engine products... nothing. my gas milage is reallyu starting to dip to. my old mechanic boss thinks is the fuel injectors but ive heard other things to. i would liek a god sugestion. i dont with to spend 1000 more because i would like to sell it next winter because i have a sts now. im greatfull for help and can also email me at ags_garza@hotmail.com
