Is there any way to test an ECU? And if I measure the lifters' preload what should the range be?
A parts house can check em but it's a cold test & some bad ones will test Ok when cold then act up when hot & some bad ones will test bad hot or cold. Do you have another ECU equipped vehicle that you could borrow it for a quick test. Preload ideal is .020-.030", post what you get & what compression numbers did you get when you tested?
