Fuel pressure at rail holds about 48psi with key on. Found intake leak in pleats of intake downstream from MAF and major coking in pcv hose. Repaired & cleaned, engine starts and dies and wont stay running at all. However if you unplug the MAF, cold engine starts and runs fine, around warmup starts running rough. Plug in MAF and engine dies, restart and it dies, unplug it and engine runs again.
Q: Is this definately a bad MAF?
