Does it happen under light throttle or heavy throttle? What are your fuel trims leading up to the misfire? Do you see a drop in fuel pressure at all? I'd be curious to know what your compression test results are.

Did you swap the spark plug or just the coil? Is it still counting misfires throughout the RPM range even if you can't feel it?

Sounds like you have a stuck VCT solenoid. I would try unplugging the VCT solenoid and watching what happens with the cam desired position data. All 4 solenoids are the same part, so you could try swapping it with a different cam and see if it moves to a the new position if you don't mind the...

P0022 means that there is a fault in the camshaft position and not a fault of the PCM command. The PCM is commanding a certain position but the camshaft is unable to attain that position.

B272C - Driver Differential Temperature Fault B272D - Passenger Differential Temperature Fault You most likely have a shorted out TED in each of your seats. You will just have to figure out which one is bad for each seat.

Did the mechanic that looked at the seat heater pull any codes from the module? You may have a shorted Thermo Electric Device in either the seat base or the seat back. The module will monitor the temperature output of both TED's and if it reads a large difference in temperature output between...

I'm not sure what that mechanic was thinking by blindly recommending an intake manifold if you showed them those codes. Anyways, some quick diagnostic steps you could take is swapping the coil pack and spark plug from cylinder 2 to different cylinders (i.e. spark plug to cylinder 1 and coil pack...

A circuit/open code usually indicates a fault with the wiring instead of a mechanical fault. I don't have a wiring diagram on hand to point on the wires you'd need to check, but I'd start with ohming out the wiring for your injector. It's possible that you have a broken wire or corroded wire...

Sounds like you are getting fuel into the evap system when filling the tank. There is a check valve in your filler neck that is supposed to seal off the evap system during fueling and there's a good chance it is no longer doing that. The car will run rough for a few seconds after fueling because...

Yes it is a soldering clamp made by Matco. I lost my other clamp and had to make due with that one. It works in a pinch but the solder feed is a bit gimmicky. I had heat shrink slid down the wires on the other side of the clamp. I've made that mistake plenty of times. I didn't take pictures of...

I finally found the time to fix my broken A/C compressor wires. Not sure who decided to run the harness like this but it was pulled way too tight.

Had to park by this when running to the grocery store.

Is the P0456 setting right away? Or does it come back after a few drive cycles? I would inspect your evap lines for small cracks in them to verify you don't have a leak. A smoke test should have shown those leaks, but that does imply the shops have tested it correctly. For the P2198: it sounds...

As the thread title states, is there anyone in the Denver area interested in trading exhaust setups? I have the Corsa Extreme setup on my '17 GT and it's just too loud for my tastes. It has the black chrome tips and the double helix midpipe. I love the tone under light throttle, but under load...

Which Fore system did you go with exactly? I noticed while reading the details of this one that the system only activates the second fuel pump when under load, so the other pump shouldn't activate under you start making some boost. This listing does advertise a check valve in the system, so I'd...

Does your regulator have a vacuum line coming off of it? 40psi may be normal depending on how it was set up https://injectordynamics.com/articles/fuel-pressure-explained/#:~:text=With%20a%20return%20system%2C%20the,fuel%20pressure%20in%20the%20rail).

There is always a chance that the car has a mechanical issue that the ECM is unable to detect, that's why we have made the suggestions to check for leaky injectors and bad check valves. I don't have a lot of faith in that tool's ability to act as an oscilloscope. But to answer your question, if...

Good. It was worth verifying. There should be a way to graph the values in your scan tool, but I haven't played with that brand enough to guide you through it. He has a physical gauge on his pressure regulator mounted to the strut tower. I agree with the general consensus that you have a...

Sounds like you have 2 problems and one is causing the other. Make sure to get your battery tested, sounds like it will most likely be bad. My guess is that your fuel system is staying on and draining your battery, but get your alternator tested while you are getting the battery tested. Does...

That should be something you are able to do with the Autel. You should be able to look at live engine data and switch your data over to a line graph. From there just observe the lines while cranking to see if there is any sort of unusual drop out.
