have done the msd conversion on my 4x4 saph as per instruction

but the car fires up but it doesnt run right it sounds like the timings out/firing wrong

ive fitted new plugs and leads and its made no diffrance

it will backfire a little and doesnt want to rev above 2k(estimated as rev counter not working)

any idea?

only thing i can think of is faulty driver

bought that secondhand
