we just put the sr in Made it RHD nice, but heres the problem it idles really nice no problem but when we take it on the street and the revs get up to about 2 or 3 grand it stutters really bad and back fires...... we check the maf and there are no sensors that are bad and the check engine light isnt on... so what do yall think..

i got pics of the rhd 240 we are doing on the gallary

 

I am only repeting what i read on another web sit www.heavythrottle.com about that problem, it suggests that you ceck for mafs mis wiring, bad mafs or a leak in your intercooler

 

spray soapy water on your i/c piping to find the leak

 

What maf are you running?

 

tried both of them didnt work
