Hi, I have a 2007 Sky Redline and I've had it looked at twice now for a P0302 code that was supposedly fixed. Each time I took it back to the mechanic. Basically the check engine light came on every time I was driving home from the shop (shop was about 30 miles away). In the first visit to the shop I got the car back and it was rough idling which it didn't do previously. The second time I picked it up, the check engine light immediately began flashing as soon as I accelerated onto the the highway off of a ramp and then stayed lit. I wasn't driving it hard, the boost didn't even hit 7PSI.

Below is the image of the service details provided by the shop.
115784


Anyways, the point of this post was to see if there were any known mechanics or shops that people have taken their Sky Redlines in and left happy with no problems. I am in the Central Florida area and have means to get the car to the right place in order to fix it. From what I understand, this is the same engine in the Cobalt SS cars, I was curious if Chevy dealers would look at the engine to figure out what's wrong.

Hi...
There’s a highly respected Kappa mechanic (kappa being the Sky/Solstice platform) who services cars in that area, though I think he’s on the west coast.

Everyone in the FL Sky/Solstice FB group who’s interacted with him come back with rave reviews.

His name is Bill Lewis. I’ll PM you his number now.

yeah I was confused looking at this receipt. I went to this shop because I was told by some friends who got their cars wrapped here that they had their cars serviced there too. In total it cost 840 dollars for everything.

Another thing I wanted to note was that I believe the shop never test drove the car. I dropped it off with 92949 and picked it up with 92949... Unless they had a way to test drive it without putting any miles on it, I dont know what they did. To say the least I was upset. I had specifically asked them to drive the car hard to make sure it ran fine. I'm unsure if there are any rules against completing requests like that but I would have hoped they would have test drove the car after looking at the engine...

$100 for "fuel system service" - that means dumping a $5 can of something into the fuel tank, with $95 profit. Jeez. Yeah, don't go back to this place again.

Double dipping on labor. R&R coil is included in R&R sparkplug. You have to R&R coil pack to access spark plug under coil pack.

Both of those labor times might be covered under R&R valve cover gasket. Or supplemental time.

TSB for this condition suggests carboned valves and fuel system/intake cleaner. They're supposed to spray snakeoil through the intake manifold, since DI tank treatment will not reach the valves. $110 diagnostic fee to look up TSB...


Before and after LNF photos with walnut blast decoking. PAW




Sometimes they can use an inspection camera through a vacuum port on the intake. Usually they will need to remove the intake just to even inspect.

LNF/ecotec walnut vacuum adapter is $30 on eBay.



That is only 1 of several possibilities (spark, fuel, air, compression)

Other options include fuel injector, valve, cam, etc.
For $30 you can do an oil lab test to detect fuel in the oil.

Static AND running compression tests are likely next.

There is no such thing as any mechanic that can repair our cars...it is a crap shoot. And if u have a R/L with a standard shift....get in back of the LONG LONG LINE.

Any BMW/mini specialist is intimately familiar with intake manifold inspection, and cleaning if necessary.

But this is also very much DIY level work.

You would be surprised what will happen if you make a PDF of that receipt, take the time to write up what you brought it in for mileage, Cost, outcome, and send it online to the Better Busines Bureau. I use them all the time when needed to take on the smallest (mom n pop ) store to the largest IBM recently. business hate being reported and respond faster than you can blink an eye. Especially if your expenses for work were extensive and the results were zilvch. You have a lot of money invested which you can most likely get back to the car fixed right. I'd demand a refund and take the car to someone a little more reilable.

Update on the situation:
I picked up the car from the same shop a few days ago. They fixed the rough idle problem on start but once again the check engine light came on as soon as I went on to the ramp for the highway. I read the codes when I got home and they are

P0011 - Intake Cam. position (CMP) System Performance Bank 1
P0014 - Exhaust Camshaft position (CMP) System Performance Bank 1

I looked them up on the forum and saw that they were related to solenoid and actuator things but I am unfamiliar with this stuff. For the other code it said it was something about VVT, timing chain, bad actuators and some other things.

Is it dangerous to be driving my Sky with these codes? Occasionally it would try to do the rough idle jiggles but it would go away shortly and I did when I was on the highway going about 80mph that when I went to try and accelerate, the car felt like it was shaking as I put my foot down (I stopped).

It probably isn't actually dangerous, but I would not drive it any more than you have to.

The codes are normally caused by clogged or failed solenoids. The solenoids power the VVT (Variable Valve Timing) actuators, so most of that is related. They could also be caused by worn timing chains or bad sensors, but both of those are quite rare.

The solenoids are located on the top of the engine, are not particularly expensive, and are easy to replace. If you do it yourself note that the exhaust and intake use different parts, so it is best to disconnect and remove one at a time so that nothing gets mixed up.

Thanks everyone, also is that the fix for both codes? Replacing both the intake and exhaust solenoids?

The car is still throwing the P0302 that it originally was when I took it in haha..... Just took the car out to see if it would throw any more codes. The flashing CEL came on after a hard acceleration from 0-50 ish think it hit 16 PSI.

As of now the codes are

P0302(again)
P0011 -
I found a video for replacing the solenoids so Ill be doing those myself.
P0014
