Your issue is related to your CPS code. The CPS provides the computer with the position of each piston in its cylinder, and the computer uses this information to fire the spark plugs accordingly. No signal = no command from the computer to the ignition module to pulse the coils, aka no ignition. Cur...

Truth be told every OBDII system cuts off fuel during deceleration. This is mostly done to reduce emissions, and protect the catalyst. Every OBD II vehicle since 1996 (in the US anyway) has this feature. Modern systems are just much more precise and can regulate fuel feed based on more variables now...

Yes, anything that affects idle. If you change any part that affects the idle speed, then you should run idle relearn. They are: Battery replacement IAC replacement TPS replacement Misfire repair (ignition, vacuum, or otherwise) PCM replacement CMP replacement CKP replacement This is what GM recomme...

Wow! I don't mean to sound negative, but, yea you SHOULD NOT be trying to drive that thing. The valves are obstructing the travel of the pistons/rotating assembly. You risk damaging a piston, rod, or rod bearing, or all of these by trying to operate the engine like this. You further continue to abus...

I would say if you continue to provide the maintenance you do, expect it to go deep into the 200k mile range. It is impossible to predict what you will or will not need. The most important thing to focus on is the details, and correct them. If you stay on top of the tiny problems, they wont grow, an...

NP... You had a connection issue I assume? I've changed more harnesses and connectors, than the sensors themselves in all my experiences with the 1.6 and 2.x liter engines.

Unfortunately, there was a lot of misdiagnosis, and wrong information thrown about. Your clutch switch was fine. Since all it does is close the circuit and allow the ignition switch to feed the starter motor, and turn the engine over, well it was working properly. Perhaps it was getting stuck, but t...

@ Daniel yes, see below... (This should be done with cold/cool engine. Make sure none of the accessories are running, including the cooling fans. Do not operate the steering wheel either) 1. Turn ignition ON for 5 seconds (key on engine off) 2. Turn ignition OFF for 10 seconds 3. Turn ignition ON fo...

The sensor was installed incorrectly. What you need to do is reconnect the sensor to the vehicle harness, but do not install it to the throttle body. Then take a screwdriver or similar, and adjust the inside ear, until it reads closed throttle specs. Once you achieve closed throttle voltage, re-inst...

Definite HELL NO. Replace the damn thing. Not worth the risk IMO.

I just posted an entire how to thread on how to diagnose, and repair this issue. Believe it or not, many times your sensor is fine, and the culprit is the connector and/or wiring. Please see my thread. Everything is in there, right down to how to check if your sensor is working in real time. Finally...

You may have installed the TPS wrong. It has a recessed ear inside where the throttle valve shaft fits into. This is how the throttle valve actuates the sensor. If you install it wrong, the TPS sensor can be giving an open throttle signal, when the throttle plate is actually closed. This can be the ...

You can check your CMP signal by running the following test: Reconnect the sensor to it's connector. Back-probe the Brown/White Ref signal wire with your RED lead, and either run your BLACK lead to battery ground, engine, or back-probe the black wire of the connector. Start the engine and pay attent...

You will need some tools to properly diagnose and fix the problem they are listed below: Voltmeter & test lead adaptors, or spare wire 10mm low profile socket or universal socket (preferred) flat head screw driver or 1/4" socket Ratchet and an extension for sockets T-15 Torx bit socket, or key, or d...

Sup board. It has been a long while since I been on. I was the on the tail-end of my studies, just swamped with little time for anything. I finally graduated in December, and things have normalized (some) now. Also my Lanos, I gifted to my GF's sister who is now studying in upstate Florida and she t...
