    I replaced thermostat valve, now heating problem gone. but shaking problem is there, One of my friend said may be this bcoz of petrol you have put means it need a 95 petrol instead of 91 for all 6 cylinders. I will check after getting empty with this. Still i have to do computer for other problem as well.

The cpu diagnostic (computer test) will check the cars computer and ll sensors and calibration, what ever is causing the problem will show up there, once it has to do with your sensors and computers and in your case i believe it does, It can be the knock or MAP sensor,

SOURCE: location of the heater control valve

There are 2 hoses going through the firewall from the engine, these are the coolant hoses to the heater core, one is 3/4" and one 5/8", the control valve should be in the larger line (3/4") which is the inlet, make sure that the valve has vacuum (heater on low), also check and see if both hoses get hot with the heater blower on low, if they do get hot your problem is not the heater control valve but the air temp control blend door actuator.

SOURCE: mechanic said valve lifters need to be replaced

valve lifters make a kind of rattly knocking noise! which sort of follow engine revs.if they are gone you may need a new camshaft as well, best to do itr all at the same time and are sold as a kit.are you sure there is a new noise or are you just listening harder?

SOURCE: 2000 Saturn SL2 - replaced ignition then BCM failed. Related?

the problem is not the bcm. the passlock security sensor is in the cylinder and housing, if the cyl and or housing was replaced the system must be relearned. if you replace the bcm you still need to relearn the system or it still will not start.

Your ignition spark control module is going bad,your coils pack are located right underneth them. this is what tells your coils packs to produce spark to your spark plugs. they are easy to replace just make sure you mark you coil pack with some tape and make sure you put them back in the same order as they came off the spark control module. Easy to replace,just make sure you use the proper size torx or socket size on the screw heads...

I know you mentioned the EGR valve has been replaced, but you may have a bad 'new' part. I know the car is electronic, but has anyone checked its ignition timing (timing belt been looked at, I know it only has 77k on it). Is the fuel pressure regulator OK and it vacumm supply?

1992 lumina starts, sputters, then dies. replaced the coil packs, plugs, wires, map censor, cleaned the maf censor. any ideas?


About the only things that you have not changed that would cause that problem are the fuel pump, the ECM, (Engine Control Module) or if your vehicle has one it could be the ignition module, and here is an image of what the ignition module will look like, and not all applications will use one.

1999 Chevy Lumina won't turn over...new battery


If your lumina has a Pass II key, it may well be the ignition lock cylinder on the steering column. The car key has a resistor staked on the sides of it which is read by the theft deterent module. The theft deterent module issues a command to the ignition relay and the fuel injectors when it reads a correct resistance from the key. If the lock cylinder is damage( broken wire) ect. the theft deterent module will not be able to read the key. Unfortunately, if you have a Lumina with a solid shroud around the steering column, the dealer will charge you $700-$1200 to replace the cylinder.
Good luck
