SOURCE: 2001 pontiac cowl pack not fireing.

Here is a diagram of the firing order for you 3800 engine. Cylinders 1 and 4 are misfiring because the operate under the same "Coil Pack" and the coil pack has unfortunately gone bad. O'Reilly sells them for between $30-50 depending on the amount of warranty coverage you want. To replace, simply unscrew the screws that hold the coil pack in place. WAIT before unplugging the plug wires. Place the old coil pack and new coil pack next to each other, unplug one plug wire, then plug it to that same port on the new coil pack. then do the same for the other plug wire. Then screw your new coil pack in place, and start you car. should run fine!

SOURCE: 97 pontiac bonneville se airbag light stays on all

Here's a quick check list for most common cost of SRS / Air bag problem.

Dirty contacts on driver and passenger seat belt buckles

Dirty contacts on seat belt connectors (under seats)

Dirty contacts on driver and passenger sides weight sensors (under seat)

Seat covers

Weight on passenger seat
(Example: grocery package trigger SRS / Air Bag light on the way home.)

I recommend you to pass an vacuum over the contacts and use CRC electronic parts cleaner to rule out connectivity problem.

I DO NOT recommend disconnecting the negative battery connector to clean the code(s).

Without the code(s) the dealer will takes "BILLABLE" time to reproduce the problem.

Please rate my answer if it is useful to you.

Cheers,

SOURCE: how to remove radiator on 1992 pontiac bonneville

Removal & Installation

  1. Disconnect the negative battery cable.
  2. Drain the engine coolant into a suitable container.
  3. If necessary for access, remove the air cleaner, mounting stud and duct.
  4. Remove the upper fan mounting bolts.

On some vehicles, such as this 1998 model, remove the upper fan mounting bolts
  1. Unfasten the retainers, then remove the upper radiator panel.

Unfasten the upper radiator panel fasteners, then remove the panel

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old. To avoid being burned, do NOT remove the thermostat housing cap while the engine is at normal operating temperature. The cooling system will release scalding fluid and steam under pressure if the cap is removed while the engine is still hot.


  1. Remove the cooling fans, as outlined later in this section.
  2. Disconnect the coolant reservoir hose from the radiator neck and the radiator hoses from the radiator.

  1. If equipped, disconnect the engine oil cooler lines from the radiator.
  2. If equipped with an automatic transaxle, disconnect the transaxle cooler lines from the radiator side tank.

PO128


P0128 is an insufficient coolant temp code. Which means the coolant temp is not coming up to full operating temperature fast enough or not at all. The fix for this is to replace the thermostat.

I have a 2001 Pontiac Bonneville SSEI, and my warning light is saying check gage. What does that mean?


My best suggestion to you is to go to Schuck's/Kragen/Chief's/Napa/O'reily's/Checker/Auto Zone and have the code read. It is a hand held reader that simply plugs into a connector in your car. They will help you do it and it is FREE. They will also tell you what the code means and is a starting point for what it is reading in your cars computer.

ABS and Trac off light coming on during drive


Usually that means either the ABS wheel sensors are defective, or the vehicule speed sensor in the transmission is defective. You simply need to find out which one, and getting the codes out of the OBD system will help find out which one usually. To do so you will need to ask someone with a code reader because the old GM jumper trick to have the check engine light flash you the code only work with older OBD-1 systems, and your 2000 model has and OBD-2 system which was standardised by government law at arround 1996.

Obd po128


That is a code meaning that your coolant temperature is too low below threshold. 9 times out of 10, you need a new sensor. It is the CTS (coolant temp sensor), or called your engine temperature sensor. Hope thats helpful

Service engine light comes on


This GM's definition of this code:
P1404 - Exhaust Gas Recirculation (EGR) Closed Position Performance
The most common reasons are either the EGR valve position sensor is defective, or the EGR valve is not fully closed due to carbon.
