Turbo Problems

Recommended Posts

Hi,

 

I'm still having problems with my car. I seem to get a lot of lag when the first turbo spins up.

 

I kind of get 3 or 4 psi boost, hesitation for about a second, then full boost.

 

Anyone know what this might be?

 

Dude put some iridium plugs out of another car into my car before I picked it up. Can swapping plugs from different cars have adverse affects?

 

I'm gonna check the plugs tonight.

 

Do Halfords do decent plugs? If so what make/model etc.

 

Cheers,

 

Paul.

I'm no great techie mate - but it sounds like your turbos may be running in 'true twin' mode.

 

A similar thing happened to me and it was down to a failed VSV (the one at the top/back).

 

Check your hoses and VSVs. If its not this......I've got no idea! I'm sure someone more technical will be along to help soon!

 

Good luck,

 

Jezza
