    Question: Running Lights

    I jusy replaced the socket on the driver's side because it showed burn marks and continually quit working. Dorman part # is 85882. It's a pretty easy fix by going into the access panel under the light. If you have small arms, you can reach in through the brake air duct and pull out the socket...

    My condolences and prayers.

    Stock Thermostat

    The L98 stock is 195*. I have no idea on an LTx.

    1991 L98-At WOT engine boggs down and nearly stalls.

    You can check your exhaust backpressure if you have a vacuum gage. Unhook your air injection check valves on the exhaust manifold and, using a rubber conical adaptor on the vacuum gage hose, insert it into the pipe. At idle, you should show 0 psi and no more than 2 psi, IIRC, at 2000 rpm. Check...

    1991 L98-At WOT engine boggs down and nearly stalls.

    you'll need a Volt/Ohm meter to do the quick check on the injectors. Pull the connector from each injector and place the DVOM leads on each leg of the injector. They should all ohm at 16.5 +/- .5. Since it will idle, also check them hot and post the readings. Odds are you have several that may...

    1991 L98-At WOT engine boggs down and nearly stalls.

    I hate to sound like a broken record, but have you ohm'ed your injectors?

    Help! 1990 Corvette starts then dies

    Code 13 on module 4 (ECM) is for an O2 sensor fault. Check the wires for burns or melting, otherwise, pull the sensor and replace. From the FSM for CCM code 13... Check for poor connections at the CCM and the DIC which could cause an open or intermittent fault. It's a pain, but pull the DIC...

    Help! 1990 Corvette starts then dies

    SIR code 35 is an open circuit in the inflator squib. Try resetting the codes and see if this helps. It is a very precise procedure and may take several tries. CCM code 13 (C for current fault, H for history) shows the fault "DIC switches open or shorted to B+." 72 - LCD Dimming output circuit...

    egr valve..????

    Jake, I don't know much about the LT engine setup, but I'm sure the EGR is easier to access than the L98. I would think that either P or N would be the last letter stamped on the housing, but that is just a guess. Sorry.

    Question: manual fan Switch

    Darn, now I'll have to burn my car;LOL

    egr valve..????

    The 90 uses a positive pressure EGR. Check this link for info on how to test. http://www.tomco-inc.com/Tech_Tips/ttt26.pdf

    Question: manual fan Switch

    I just checked the electrical supplement for my 90 and it shows light blue/ black wires for both relay coils, that are grounded by the ECM. I then checked the car and have a dark blue/white and light blue/black. So much for accuracy in a FSM...

    BCM

    Two ways.... Go to Radio Shack and buy a variable resistor that will cover the range of the 15 possible keys(I don't have the list handy, so you'll need to search). It will be time consuming as you have to wait 3-5 minutes after trying an incorrect key, before security resets. Once you find the...

    Help! Houston we have a problem!

    The '90 does not have a temp sensor in the EGR tube. If the diagnostics lead you to replacing the EGR valve, make sure it is a Positive pressure unit. (There will be a P at the end of the part numbering).

    turn the key and starter does not engage

    Bob, Looking at my FSM, I also see that the LCD (5 amp) feeds the radio control head, along with the wiper and radio fuse...??? Have to be an electrical engineer to figure out their reasoning, I guess.
