    How do I complete a readiness cycle with 1.4L T 6-speed MT

    I have a 1.4L turbo 6-speed manual transmission and I did not modify the exhaust system. I first failed emissions testing and found out that my cat was bad with a P0420 code. I replaced the front cat and the code didn't return, my power returned and my MPG returned to normal. I ran a readiness...

    car suddenly wont start

    I had this problem and I thought the start relay was bad. I replaced it and the problem was still there. I then remembered seeing one symbol that kept showing up on my instrument panel. The owners manual didn't say what it was. I googled it and found out that it was the theft deterrent system...

    car suddenly wont start

    This is just what I was looking for. My 2014 LTZ 1.4L with 105,000 miles on it has now reached this problem. I searched all through the web for possible causes. I have the same intermittent no crank in the high/low ambient temps. This part number is helpful, I'll give it a try.

    Squeaking sound and P1101 P0507 codes

    Trouble codes: P1101 P2227 P2228

    My car finally reached 50,400 miles and then the codes came. Symptoms: very rough low idle and nearly on the verge of shutting off. The first code came with P1101 and then I assumed that maybe it was the mass air flow sensor. So, I took it out and inspected it. I didn't see anything wrong. So...

    Mass Air Flow sensor removal

    I have a P1101 trouble code and it appears that it's a MAF problem. I am interested in taking a look at the sensor to see if it's faulty or dirty. I have 1 problem. I can't figure out how to disconnect the connector. I saw some sort of red clip and slid it, but the connector doesn't come off...

The engine and transmission indicator lights turned on in the dashboard and I heard a warning chime. I turned the car off and then on. The problem...

    I may have lost an ignition key

    I'm looking all around and I think I may have lost one of the two ignition keys that came with my car. Does anyone know the cost of a replacement key and if I can't find the key, should get a new one from the dealership?

    A bad engine seal on a 2 yr old sonic, already?

    I was going to announce my 2-year update on my car, but after I changed my oil, I looked at my oil pan and noticed a very slow drip on the adjacent side of my oil pan from where my plug is located. I touched around the side and felt oil on the sides of the pan. Shined a flashlight up around the...

    18,000 miles and Chevy wants to service for $400

    The car only has 18,000 miles. It works just fine and during my free oil change they looked for reasons to charge $400 for services I don't need. I bought this car 1.5 yrs ago as new with the intention to not keep dumping large sums of money into it every year like with my old car. This is what...

    I was driving down the highway today and suddenly my manual transmission dropped into neutral. I tried to shift back into gear and it wouldn't. I managed to drift into the shoulder on the highway. I thought the engine shut off, but it didn't. I tried turning the engine off and back on. It still...

    leak in windshield washer fluid tank

    my windshield washer fluid tank is leaking fluid from the pour spout tube that connects to the top of the tank. I noticed a rubber seal that's on the inside, so I pulled up on the spout tube to see if it seals the leak. It is only a temporary fix, since any vibrations will knock it loose...

    I have a 2014 Sonic LTZ, 1.4L Turbo. I went to a chevy dealership to get my first oil change. The warranty says that they are supposed to replace the oil with acdelco dexos1 synthetic oil. My invoice says Premium motor oil. And the sticker on my windshield says to return in 3000 miles. I'm...

    Chewed O2 sensor wires?

    I received my UltraGauge to view recent trouble codes. They all pointed at the O2 sensor. I looked inside the engine bay and found that the wire casing leading to the sensor looks as though it was chewed in 3 places. The wire casing didn't look burned and nothing rubs up against it. Do...
