before u replace any parts u need to have the electronic engine control tested for trouble codes, this is the 1st thing that any shop does to know where to start the repair and diagnosis. Most likely u have a defective crankshaft position sensor, but have the test run..

Airflow sensor is bad or dirty.

there is no linkage there is a cable fron the transmission to steering column nylon gromets on each end break replace shifter cable

You might try removing the battery terminal for 10 mins. Than reconnecting. If that doesnt work you may have to take it to dealer to reset the system.Hope this helps.

I had a 99 with the same problem, and suggest you check under the passenger side front carpet. Remove the flat door kick plate, lift up the carpet on the front passenger side floor and you will see a large wiring harness running along the floor, wrapped in black tape. Water and salt gets into this harness and will rot out several wire splices that you will see. Look for wires that run from 2 wires down into one (under black tape.) These are spliced together, and rot out. There was several large gauge wires/splices(windows up and down) and I think 2 very thin wires/splices (lock/unlock) . Even if the wires look connected, give them a good tug, they will come apart and be green with corrosion. This is a very common problem and worth the effort to check out. Repairing these splices fixed both the power windows and locks at the same time. Good luck

what is the sensor in tranny?

Could be a relay check for a starter relay and change it.

I think your car is runing Lean and i would say check the Mass air flow sensor and the fuel system because your car seems like its sucks more air then fuel. Do you have any check engine light on ?

MOST(!) of the time, it is the pressure sensor that has failed. If the engine does not seem overly loud (it will, without any oil pressure), I would say this is your problem. If you aren't sure you can recognize the sensor (it will normally have a single wire and a hex fitting for removal), I suggest you buy a manual for your Montana and the pressure sensor at the same time. I like Haynes manuals and they can be found on line, at eBay or sometimes, even at a local library. If, however, your engine IS loud, it shouldn't be driven under its own power at all until the source of the failure is found.

I suspect an ignition switch problem, you need to check to see if when you try to start it if there is power to the signal wire at the starter. If there isn't, check the same wire at the ignition switch, if there still is no power, check to make sure the grounds from the firewall are secure and they have near zero resistance between the firewall and the negative battery post. Check to make sure there is power getting to the ignition switch, if there is none, then you have a broken fusible link under the hood

No.The brake warning light could be telling you there is a problem with the hydraulic brake system or the parking brake.The trac off light is saying there is a problem with the brakes or engine and the traction control system is disabled.
