engine stall (for short time)
First: a short introduction. My Name is John, I am from the Netherlands. So,
if my Englisch is not perfect........thats is why ;-)
My problem, and I will try to be as specific as possible;
2 months ago I bought a new 2017 Camaro 2.0 Turbo (6th gen.). After a few
weeks the engine started to stutter and did not accellerate. It also made a
"peng peng" sound during acceleration.
When does it occur?:
When i leave to work in the morning there is nothing wrong. (My camaro is
parked in a garage). I drive to my work (18 kilometers) and park my car at
work. When i leave home (9 hours later), i drive from the parking area to the
street. This takes more or less, 20 seconds. Then, when I am on the road
and start accelerating, the engine stutters, will not accelerate and makes a
"peng, peng" sound. After 3 or 4 seconds everything is normal and the
problem is gone and does not occur again. It does not matter if it is raining or
the sun is shining, after my Camaro has been parked for a few hours, the
problem is back again.
The dealer where i bought my Camaro, updated the software and replaced
the spark plugs but the problem is still there. Tomorrow i will bring my
Camaro back for the third time but they do not know where to look or start. It
is an official Chevrolet Camaro dealer and they say they looked in the
database of Chevrolet but my problem is unknown. I am concerned that my
engine will be damaged so I hope someone can help me with this problem.
My Camaro is fully stock, no modifications an i use gasoline Euro 98 (octane
/ RON 98).
I made a sound recording (mp3) if it will help.
Thank you very much in advance.
Kind regards. John
Can you try a different formulation of gas, with a different octane? European 98 octane is the equivalent of US 93 octane. I assume the dealer knows to tune these for the octane you are using? I do know here in the US, if you tune for a higher octane, you do not want to dump lower octane in it, you will get pinging. So maybe your gas station is selling bad gas, lower octane or has water in it?
KenF, Euro 95 (US 91?) should be enough so i use a higher octane than necessary. And it is a Camaro for the European market so i asume it should be OK.
Yes, BUT if the gas station you are buying gas from has a leaking underground tank, or poor quality gas, you may be running at a lower octane that you think. Try some octane boost to see if problem goes away, or switch to another gas station.
@ KenF In the mean time I have tried 3 other gas stations and I used both Euro 95 as Euro 98 but the problem of feeling power loss, the stuttering and the "peng peng misfire" sound are still there. I got the sugestion to make a longer trip so the engine and exhaust could heat up. I was sceptic about it because (in Europe) a lot of (turbocharged) cars drive about 20 km, if people go to work for example. And before my Camaro I drove a Nissan 350Z and I had never problems driving to my work..... But I want to try everything for a solution so I drove 300 km in manual and held the engine above 3000 rpm to heat up everything (faster). After the trip the feeling of power loss and stuttering (when the engine is cold), seemed less. The "peng peng misfire" sound was gone........ for 2 or 3 days :-( It looks like the feeling of power loss and the stuttering is a bit less but the "peng peng misfire" sound did not disapear. Monday i will contact my Chevrolet dealer again.
Because it's a brand new car, let the warranty cover the work. We have a saying here, "the squeaky wheel gets the grease." So if you keep after the dealership, they will make the car right. Pester them day and night if you have to.
