    2008 Chevrolet Aveo Misfire uphill (Chevy Again)

    So very strange, the issue seems to have gone away or at least diminished since last we checked. I asked our friend how was the car doing, and he said it is running better. No changes were made. I took the car for a stroll and the same hill that caused so many issues, it survived. The check...

    2008 Chevrolet Aveo Misfire uphill (Chevy Again)

    So, the issue remains. Although the severity has decreased in recent weeks. After a few rounds of injector cleaners, it does not happen as much as before. But, I am left with the following theories: - Injector issue. Is it possible that injector 2 is not flowing enough under high load? -...

    2008 Chevrolet Aveo Misfire uphill (Chevy Again)

    update: What I previously called the EGR was actually the intake flap control. When I blocked it off, the code came up for manifold control. I replaced that hose and now the car runs better (lean instead of rich), but the issue remains. Typical logic would say that cylinder 2 has lost...

    e85 ethanol gas in 08 Pontiac Vibe

    I do not suggest anyone go full e85 in a daily driver car. I just wanted to share the story. 50k miles still going strong (except when its cold).

    Is Fram ultra synthetic a good oil filter for a 2001 Toyota Camry?

    Mobil 1 plus OEM filter is the go to. The price difference is minimal.

    03 Honda CR-V loses oil like crazy!

    I have had 3 cars that burned oil and you would have never known. No smoke or anything. It is usually a PCV or something like that, but sometimes just poor mainenance causes scratching of the cylinder walls which lets oil get through. If that is the case, there is not much you can do other...

    2008 Chevrolet Aveo Misfire uphill (Chevy Again)

    I bypassed the driver side vacuum lines to see if that might help. The vacuum line to the EGR was cracked. After finding the cracked hose I went AHA! But, the issue remains...

    e85 ethanol gas in 08 Pontiac Vibe

    In a pinch I could put a gallon or 2 of regular gas. But if you were to say just fill it up with regular gas it would start but not be very drive worthy. Too much fuel with the bigger injectors.

    e85 ethanol gas in 08 Pontiac Vibe

    The overal fuel trims came out to a less than -10% long term trim across the board. The injectors matched what it needed. But the first start in the cold (I assume) does not compensate the same. During the day it is fine, it is only if its really cold out the OEM ECU adds extra fuel and it...

    e85 ethanol gas in 08 Pontiac Vibe

    I am new here but I have several car stories you might find interesting. In this case, I switched to E85 gas in my 2008 Pontiac Vibe. Some of you may know that the Pontiac Vibe is basically a Toyota Matrix sold by Pontiac. It uses the same Toyota engine as a Corolla of similar year. I did...

    2008 Chevrolet Aveo Misfire uphill (Chevy Again)

    I see. I am used to older cars without the "misfire" calculation. In the meantime, I put the camera on Cyl4 and it is also clean along with the #1. The cross hatching is beautiful, I wonder if the engine was rebuilt because it is unlikely with 120k miles for the head to be so clean. The...

    2008 Chevrolet Aveo Misfire uphill (Chevy Again)

    One would think so. I monitored o2 voltage going uphill and it hits .85v which is pretty close to pig rich. If you let off the gas it takes about a minute to get back into normal range. But agreed if it was super rich it should be black in there not squeaky clean.

    2008 Chevrolet Aveo Misfire uphill (Chevy Again)

    Update: He let me use the car to drive around and try to figure out the problem. It now just goes into poop mode at anything over 40ish MPH at part throttle. However, if you punch it full throttle you can go 50MPH no problem. I did a freeze frame check on the scanner at it shows 45% throttle...

    2008 Chevrolet Aveo Misfire uphill (Chevy Again)

    On to the Coil: Since the plugs did not fix much, I went ahead with the coil. I did find around the #2 post there were white marks which looks like escaping spark. Also some of the oil leak had sprayed over to the 2/3 post. Part of the plastic was missing from the top of the post. I thought...

    Keeping external drive plugged in to desktop 24/7

    Computer people debate this all the time. Do you leave it on forever or only plug in as needed. In my experience over years, the power cycling tends to have more more of an effect on a device than the constant power. But, if you don't use it for a couple of months, do you really need it on...
