L67

[Chris Collier]

My vt v6 supercharged does a half stall when engine is cold and trying to accelerate from dead stop have cleaned throttle body and checked for vacuum leaks and still does it

Clean the MAF and run some injector cleaner.

Check your plugs aren't cracked and are gapped correctly.
L67's are sensitive to weak ignition systems.

Plugs,leads,coil packs are all brand new and clean MAF even tried swapping the MAF but had no luck

 

[Chris Collier]

I always run premium and run injection cleaner once a year

Was the miss there before you touched plugs and leads?
Go back and check you didn't crack a plug when tightening them by accident. I did it on our old L67. Also confirm they are gapped correctly as they run a smaller gap than the Ecotec.
I also noticed that aftermarket leads caused me headaches too. Went back to the originals and they were miles better.
