2G Engine problem - Don’t know why...

[Heryst78]

Hi guy’s,

Today, my GST did something new.

I explain :
I moved it from the garden to work on it. It starts smooth, i drove it to the garage to work on it.
Everything was fine. I started the engine 2 hours later, and it did the same this in the YouTube video below (it’s my car)

You must be logged in to view this image or video.

Timing belt is new.
The only abnormal thing is that my fuel tank is almost empty.
My air fuel ratio is near 17, at normal time it is at 14.7
The exhaust put water outside.
And once on five, this engine starts with difficulties...

Any ideas ?

Thanks, and sorry if my English is bad, I am from France

Sounds like a misfire!! But that’s my opinion. I’ll allow the others to chime in that are more experienced then me.

What does that fluid smell like? Sweet smell= coolant, fuel, well= fuel.

Wondering if you have a dead cylinder or stuck open injector?

Id do a compression check and investigate everything: check coolant, fuel related items, throttle body, pull plugs and check what they look like etc.

Definitely sounds like a misfire, but not a misfire due to spark. Check your fuel system parts for sure.

Check the MAF plug, also check injector wiring. One of my injector wires came off a few months ago and it ran like that. Boost leak test it too while you're at it

Yea sounds like a cylinder is completely dead....I would start with the plugs n wires....that area
