re:valve lash

Thanks DOUBLEVISION. The old fashioned vacuum gauge is the best tool to identify engine misfires. I worked on a 1996 Mitsubishi Mirage for codes for misfires that was at another shop for a month. The customer was told it was most likely a plug wire or cap or rotor. They had already installed spark plugs, 2 Cat's, 2 O'2 sensor's, and had it at the dealer for a computer reprogram. It had a miss at first start in the morning. I shut it off and installed a vacuum gauge and re-started it. Guess what, a valve lash adjustment cured it.

Note: this car is junk. Even the Dealer could not get the Readiness Monitors to set to ready to be able to pass smog. The computer is going to sleep, and the cost of a new one would excede the value of the car. Glad I don't work at that shop, my shop's landlord's son owns that shop, and boy is he mad.
