set up: 97/98 jdm b20b with p74 ecu in a obd2 car.
ive got a engine code 8 from the jdm b20b.
code 8:
(p1359) ckp, tdc, cyp sensor
(p1361) tdc - top dead center intermittent interruption
(p1362) tdc - top dead center sensor no signal

all i know its a code 8 but i dont know which (p1359/1361/1362) it is.

this code came on after i did an engine shampoo and only covered the filter but forgot the cover the ditributor. maybe water went in the distributor and spark plugs. the code is also causing my rpm needle to flutuate b/t 1000 and 1300 rpm at idle (normal idle at about 800-850rpm) and the oil pressure gaude to fluctuate around 50 psi where at idle normanl its at 25 psi.

how bad is this? and is it safe to drive for a few days before i need to replace any parts (distributor)?

anyone had a engine light or a code 8 come on after a clean engine shampoo?
now im so worried.
please help.

thank you.
