sometimes it has power sometimes not.

My 93 om602 is often sluggish. On occasion, especially when thoroughly warm it has a lot of pickup. It is like night and day. I feel like its a vacuum connection somewhere that seals up when warm but not always. Ive replaced all vacuum connectors and vacuum system wide seems normal. The difference really feels like its an N/A vs Turbo sometimes. Could it be the ALDA? Waste gate actuator? where to start?


Before I start turning every stone I figured i'd ask.

Thanks guys.
