1994 Chevrolet Lumina APV QuestionsRefine by vehicle
codes as follows: 22 1/4 TP volt low reading is .77-.80
24 2/4 VSS no signal
33 MAP sensor high reading is 29 KPA volts.97-.99
45 O2 high volts reading is .07-.99
we have also installed a new MAP and TPI sensor and run Sea Foam thru both fuel tank and and injectors on top of motor.
we are trying to track down cause of a lean O2 sensor,a bad maf is listed as one of the possible causes. does this even have one? I see them listed in the Chiltons as on only a 3.8 motor.
fans will not come on
when i start the van i have to rev the engine to keep it going or else it will stall. i have to keep my foot on the brake while keeping the RPMS up so that the engine will not stall. on the freeway there is no problem as the van RPMS are up and the alternator is suplying juice; however when i slow down or take my foot off the acclerator it will want to stall and i see my voltage meter drop. i am at my whits end with this van. i replaced the battery and alternator yesterday,i have resealed upper and lower manifold gaskets, new spark plugs in the past 3 months, new fuel filter in the past year, new MAF sensor, new idle air control valve. i have no idea what would be causing this. please help me resolve this it is my only vehicle.
Trying to replace brake light bulbs. Looks like a clip inside and don't want to break it.
While driving, my high beams were on, the lights went out,(Side lamps, blinkers hazards all sill worked) I franticly jerked the high/low switch on the steering wheel they came back on went out again and now they dont come on. The switch turn the inside lights and side lamps on they are all fine.

I only have a problem starting when its wet out and my van has sat more than 8 hours. I was told most likely a crack in the distributor cap.Any ideas or suggestions? Also any step by step instructions how to change cap and rotor as I;ve heard they should both be done.
