1997-2001 Honda Cr-v Misfire flashing check engine light P1399 P0300 Poor idle B20 B18 civic Integra

The dreaded P1399 and flashing engine light. This applies to all 90-01 civic, del sol, Integra, accord, prelude, s2000 that require valve adjustments. Most of these vehicles do not get their valve adjusted often enough resulting in a burnt valve. If you are experiencing a rough idle and flashing check engine light do a compression test FIRST. Chances are it’s too late for a valve lash but don’t be intimidated! Anyone can do this with basic tools and only cost roughly $350 instead of thousands for a cylinder head replacement/valve job. Then with the tools and knowledge, you know how to help your Honda buddies also save money and keep these cars from getting crushed possibly

Damn it’s crazy how this happens to B20s, same story with me right now got a B20B with 80k miles and I was thinking that must be nice and maintained but nope it was definitely not
