Knock Knock. Whos there? Engine Trouble...

ok so my prelude was beaten as a child by its previous owner. i picked it up with the following:
-2qts low on oil
-Codes thrown for: knock, cat, auto trans failure, transaxle.
-previous owner ran 89 octane gas for a unknown period of time.
-feels sluggish at low rpms and will skip 2nd gear sometimes in d4.
-low on coolant and was running a few marks over 1/2 on temp gauge.
-hole in power steering hose and leaking fluid all over back of the block.
So if the powersteering fluid is leaking on the back of the block could it possibly get on the knock sensor and cause the circuit malfunction? also i think because its loosing minimal amounts of oil and coolant the head gasket needs attention. there is no smoke coming out of the exhaust at this time. and wtf does auto trans failure and the transaxle trouble codes mean?

Re: Knock Knock. Whos there? Engine Trouble...

i'm not a mechanic man, but i think there might be bigger problems than PS fluid leaking onto the knock sensor causing a malfunction. I was always taught to troubleshoot problems by fixing the cheaper issues first. It wont hurt to replace the PS hose and get a new knock sensor, but i wouldn't be surprised if you had the same knock sensor code pop back up. 2 quarts of oil down and low coolant is not good for a motor. Auto trans failures are common at least for 5th gen ludes. Good luck tho and post up if you find any other issues.

the knock sensor is more than likely from him running the 89 octane.

I hope you got it for a very good price man because your going to have to put some money into it. Your auto tranny is probably going out. You most likely will need a 5 speed swap

Re: Knock Knock. Whos there? Engine Trouble...

I traded A 98 GSR that needed some work. so i think i traded one problem for another. the prelude is running alright and not giving me many problems aside from the CEL light and the trans acting a bit slow. the car temp is normally at 2 marks under half though. is this normal for the h22 cause all my other cars normally run about 1/4 of the temp gauge.

how does one repair such nonsense? if the knock sensor is throwing that CEL that would mean that it has retarded the timing right? so wouldn't i just have to change the timing belt and re time the motor or what else? idk much about the knock system.
