Check Engine Light Code P0300 On GM 2.2L and 2.4L
We have been seeing quite a few problems with the GM 2.2L and 2.4L engines. Mostly on model years 2005 through 2009. This engine is very common in the Chevrolet Malibu, Cobalt and HHR. As well as the Pontiac G5 and G6. This is the 4 cylinder. The problem I am going to talk about today is a check engine light and misfire codes. Car…
2003 Olds Alero Transmission or Catalytic Converter Problem
I have a Oldsmobile 2003 Alero with 67000 miles on it. Yesterday the speedometer started going up and down by itself and wont register. Also the car jerks if you go past 30 MPH and it feels like the speed of the car has to catch up with how hard I’m pressing down on the gas. Any ideas of what could be wrong. ProTech: Sounds like…

Question: I have a 1999 Ford F150 V6 it give a check engine code saying a misfire on cylinder 6 but it doesn’t do it all the time.

2004 Chevy Impala Engine Misfire Code P0302
I was getting a P0302 indicator code for # 2 spark plug. I changed the wire and it went out,however when I got up to 35 mph the check engine light would flash until I got below 35 mph. I decided to change the other wires and that’s when it started to backfire and wouldn’t allow me to accelerate pass 10mph.Did I put the wires…

Oil and Coolant Mixing In Engine- Pictures
I had the pleasure recently, or displeasure rather, of getting a customer’s vehicle that was overheating and running very poorly. Once I got in and started it up, I knew it was going to be pretty messed up. The engine was knocking, misfiring, and almost immediately going into the red on the temperature gauge! I pulled it in and the first thing I did was…
Spark Plug Failure Causing SES Code P0300
One thing I see quite a bit these days, is vehicles coming into the shop running badly, misfiring, check engine light code P0300 and getting very poor fuel economy. Usually upon a test drive, I’ll find it stumbling on acceleration. Back at the shop, while checking for trouble codes there will most times in fact be multiple codes for misfires. This is often due to…
Chevy Silverado Engine Ticking Noise
I’ve heard many complaints from customers, in person and online, about a ticking-type noise coming from the engine on their Chevrolet Silverado. Usually at start-up it is loudest, and this may even cause a misfire condition on a particular cylinder. The noise seems to be rotational, usually about half the speed of the crankshaft. Lately, I’ve seen a few of these in the shop, and…
