I'm borrowing a scan tool from a friend this weekend to check out what's going on inside. I'll look at the misfires. Does the computer store this value, or only check it while the engine is running?
Would the scan tool show the lean mixture or ignition timing issues, if present?
Can you (or anyone else) recommend a good, not overly expensive scan tool that that will interface with my laptop?
Any easy way to check for a broken valve spring? Also, are these interference or non-interference engines?
Thanks for the tips.
