I got this problem with this 87 Turbo-T I just aquired. Puzzling....
I'm getting knock starting at 5 PSI. Turbo-link spiked at 30 degrees of knock. With that I should be hearing it! But there is no audible knock. The car doesn't skip a beat! Pulls real strong!
I do know I need a new O2 sensor! I'm getting a malfunction code telling me so. Also, the O2 readings are all over.
My question.... Since my car is not getting the proper O2 reading, it must be running rich and with that getting knock? Or... should I start thinking about a new knock sensor?
Any suggestions???
Oh, by the way. completely stock except the Kenny Bell intake.
