    88 Clutch Slave Cylinder Premature Failure

    Recently the clutch once again became soft with little travel for disengagement. Clutch fluid is dark, so I suspect that the slave cylinder has been contaminated with clutch dust. Upon inspection the clutch actuator rod boot that plugs into the bell housing is damaged and has probably resulted...

    88 Acrylic Roof Panel

    Thanks, I reviewed the procedure stipulated in the maintenance manual for disassembly. but it is unclear with respect to where the acrylic panel adhesive is located. It may be that the adhesive is located sporadically as opposed to a continuous bead between the frame and the panel. Can you...

I want to remove the cracked panel and replace it with the spare. Has anyone ever managed to disassemble the roof panel from the frame and do a swap from a...

    Question: 88 Coupe - Emissions Test Failure

    The ECM does not set any codes unless forced to do so by a simulated failure of a sensor. I use the WIN ALDL 160 Baud reader to view ECM parameters. The ECM sets a rich flag that the software recognizes. As soon as the engine goes Closed Loop the BLM drops from 128 to 108. Thanks for the...

    88 Vette Slave Cylinder

    Has anyone ever managed to retrofit some kind of a dust boot to the slave cylinder for an 84 to 88 vette or has anyone created an adaptation of a later model year slave that has a dust boot as standard equipment. The 88 with its 4+3 transmission has a different bell housing than later...

    Question: 88 Coupe - Emissions Test Failure

    I agree that it is unlikely I have any leaking injectors based on the test results. My 88 does not have a MAP sensor. The TPS is set to 0.56 Volts and is stable. This one is truly a mystery. WTS

    Question: 88 Coupe - Emissions Test Failure

    Subsequent testing has revealed a normal output from the MAF for the engine idle. Fuel pressure holds for a considerable time after the ignition is shut off, so I do not think I have any leaking fuel injectors. I have looked at all engine sensors including MAT and Coolant sensors and all have...
