Hi Mate,

 

I need some help.

 

My specs :

Supra TT 1994 Euro spec (same UK)

Engine stock with oem twin.

73'000 kms

 

After 2 years, with a little kms done, my engine do strange accceleration.

 

2013 : Past year, 2nd turbo have difficult to boost (engage and cut ???) but after warming and some kms done, my car reboost like a charme.

Some days later, test and same problem.

 

2014 : Take time to fix the problem, i have change some vaccum hose with no change :(

Today, i have put new coil pack and change the plastic connector, no change.

 

At low rpm, i have strange vibrations, my exhaust smell fuel !

 

Thanks in advance for your help and tips ... sorry for my bad english.

 

Regards,

 

Alex

sounds like a knock, but when at back sounds like a plug/coil pack gone...

 

Coil pack and connector plug are new.. :think: , same sympthom with old or new. I need to try to remplace sparks plugs. They have 4000 kms, look normaly, but 4 years old.

 

What do you think "sounds like a knock" ? sensor defect ?

 

Thanks
