Did you check for spark ,fuel pressure , compression ? Check base engine mechanical systems

Have the cooling system pressure tested ! 3.1 l engine These engines had intake gasket problems , have the radiator cap tested as well . Bad radiator cap will allow coolant lose . Does the oil cap have whitish or dirty color foam on inside ? Coolant leak into the oil .

It may be possible that flushing the transmission fluid is your problem. Was the fluid really dark and had a slightly burnt smell to it? If the answer is yes, then you probably had an issue with the transmission and didn't know it and the particles suspended in the transmission fluid were what was giving it enough friction to make the shifts, by changing out the fluid you removed all the particles and now the transmission slips and won't shift into certain gears. Just a guess given the information you have provided. I would look at the transmission for the issue.

Codes that light check engine lamp are emissions/engine performance related only. Your DRL and SDM both talk to the ECM for inputs (they need to know if its running), but they dont affect the engine or tell the engine module to change how it runs. Your ABS can affect how the engine runs as it sends wheel speed information that is used to adjust engine output, transmission shifting, and fuel/timing in some circumstances. Check the ABS module for signs of water or oil affecting it, or water in the connector plug. Also check the harness where it leaves the module to make sure it isnt rubbing thru anywhere you can see. GM ABS modules are not uncommon failure items, however mostly they set module fault codes or motor amperage/function codes. Id start with further diagnostics of the ABS. NOTE: using generic OBD2 scan mode will show you only codes that are check engine lamp related if you want to be sure. Enhanced scan mode shows you any and all, and some of them simply have nothing to do with the engine lamp being on.

I don’t know what these other people are reading, what they think you’re driving, why they’re posting directions for an Equinox, or pictures for anything but the 2001 Malibu does NOT have a cabin air filter!
It did NOT come from the factory with one or a pace to put one.

Source: I own a 2001 Malibu LS and have turned almost every nut and bolt on that car.

Contrary to what the other person wrote, the 2001 Malibu does NOT have a cabin air filter.
It came from from the factory with NO provisions for one.

I would start by checking for a blown fuse

No ,it's not a vacuum problem . Something electrical more then likely . Crankshaft postion sensor's A or B going out or the ignition control module .Your best bet , take it to a qualified repair shop that has the proper diagnostic testing equipment ,tool's . To view engine sensor scan data. 047 Engine Hard to Start or No Start Scan Data for Ignition , not saying your's is hard to or no start . Just for demonstration purposes only .

First change the wheel/tire with the spare or another wheel tire to check for any change in shake.If the shake is in the seat it is usually in the rear,if it's in the steering wheel,then the front. If the wheels are balanced all bushing could be loose and it will still be a smooth "no shake" ride. Don't forget if brake discs and brake drums are out of balance no amount of tire balancing will correct a shake. Also there is static and dynamic wheel balancing machines.You always want a motorized "dynamic" wheel balance done.

The HAZARD LPS fuse in the left hand instrument panel (LH IP) junction block supplies battery positive voltage to the flasher module, which is part of the hazard switch assembly. This is a pontiac , but yours is close . Pull the panel apart

Bad installation methods... take it to a qualified professional.. sounds like one of the connections has come undone...

Back to the mechanic - sounds like either an IAC motor or TPS sensor is the problem, but also could be the throttle cable (sticking leaving the throttle not fully closed).

if the unit is overheating ( your statement mentions burns , breaks etc that indicates that something is drawing excessive current through that unit a possible fix is to use a rely in that circuit if you cannot find the reason for the excessive current draw failing ac clutch coil would be a good place to start looking

I think i know the issue. I have had it happen to me it is your security system failing. Your car is on the list year make and model... I found a module that you can install yourself and it will bypass it allowing your car to start everytime.. Check it out and ask questions they are very helpful. Also for some reason if it does not work they will refund you %100 of your money.. this literally saved my car. Hope it helps http://vatspasslockpasskeysecurityhelp.com/ Do It Yourself GM Security bypass
