pulse.......

hey guys me again so i have a unique issue, when im accelerating my engine power pulses. like lets say im going about half throttle for ten seconds, for about 5 seconds i will have the power im asking for and for the other 5 i will have about half of that, alternating every second. any ideas?

Split in boost hose?

wherre is that located

any rubber or plastic pipework between the turbo and intercooler and intake manifold.

to add to the problem my lights dim in and out when it happens

Lazy N75. Check your boost pressures when it's occuring.

Is it only when accelerating and not when cruising?

I'm betting on a boost hose, or a restricted intake, or an old fuel filter.

Lights dimming would be an alternator or ground issue.

Which could stall or brown out the ECU and affect driveability. Chaffed wire hunting season?

dang ok well my intake has never been cleaned
