got a problem on the s1...the car jerks alot when turbo is kicking in and doesnt go after 4000rpm...it just loses power...

im suspecting its the spark plugs because i had them changed when i had my service done but crappy cheapy ones were put in...

also apart from the ecu pipe could there be anything else to check.??

cheers

 

Has this only happened since the service?

 

well...urrrmmm.....i had the engine rebuilt and done my 1000 run in miles and had my service done....so this is the first time i have really kicked the turbo in...the car defo is running rich because it hasnt been setup yet but im thinking if it is the spark plugs or pipes or something get it sorted before i get it on the rollers for a tune.

 

actuator might not be set up

 

what do you mean?? how do you set it up?? i did have the turbo changed so coul dit be that it wasnt put back on properly...it is a -31 one.

 

Change the plugs for the correct ones.

A lot of people do not realise how important it is to have a plug with the correct heat range fitted. If the plug over heats then the earth electrode can start to glow. This is a hot spot in the combustion chamber and can ignite any fuel which comes into contact before it is due to be ignited by the spark. Det occours and good bye pistons.

Once you get the plugs in, see what it drives like. It is possible that the plugs have been set too wide and the spark is being blown out or it may have fueling issues..

 

oh well got it booked in for setup so we'll see how it is after that...
