Hello everyone. Just joined the board and just picked up an extremely nice 1988 Thunderbird Turbo coupe 5 spd. I know very little about these cars, but have a vast knowledge of turbo cars and cars in general. I gotta say I love this car already. But anyways, to the point.
When I roll into the throttle, right before it see's boost I hear the engine knocking, then as boost kicks in, it goes away. It's like the the added 1-2 PSI before it boosts doesn't get read and it either doesn't add enough fuel or doesn't retard the timing. I'm running 92 BP gas in it. The car sat for years and I have run two tankfuls of gas through it.
So, in order to figure out the problem I would like to know how this system works. Does it have a boost sensor on it and does it use that sensor to also retard the timing? Also what exactly does the premium/regular gas toggle switch do?
