Hello.

I am writing from finland, sorry my bad english

I have 87 rst, and my problem is that when accelerating 0.1 boost even car stops going, and bopping (misfire) in the exhaust.

Spark plugs are white?





I have tried other motorcraft ignition box and air tempeature sensor.
The car runs about normally when i limit the pressure that goes in ignition unit.
I think car runs lean, turbo is very hot and red when driven even little at boost 0.5 bar.




That filter and bleeder are needed it even works at 0.5 boost and half gas it misfire, but full throttle and lot of revs it works.

I think car should work normally without any limit of pressure in ignition unit?


The car has some modifications:

Dumpvalve
Larger intercooler
Kent cams cvh 31 camshaft
-34 actuator

I post some pictures of engine bay, help needed

i have not try new spark plugs and spark wires
