I just did a bunch of things, pretty much preventative/to help pass smog in CA. New plugs and wires, removed and cleaned the exhaust manifold, IAC and throttle body, plus new flame trap, hose and housing. Yesterday I undid the intake manifold, replaced the heater hoses (loosing a half gallon of coolant on the garage floor while trying to get the lower hose off), replaced both the coolant temp sensor, and the temp gauge sensor, and installed a new intake gasket.
In putting her back together I managed to strip the rear most stud. It was getting late, so I just buttoned her all up minus the nut on that last stud. Today I drove her a few blocks to the coffee shop and back and noticed the temp gauge reading higher than normal (temp comp board has been removed/overridden). Checked fault codes and I get a 2-2-4 and a 2-3-2, which I believe is a faulty coolant temp sensor, and a faulty IAC.
A few questions, I have extra exhaust manifold studs that didn't need to be replaced, are they the same as the intake manifold? What is the trick to removing the stud without breaking it? Could the intake manifold leak be leading to the IAC fault reading, or did I somehow kill the IAC with cleaner when I cleaned it? I suppose I should check the wiring next, both to the IAC and the coolant temp sensor. I noticed a weird, hard crimp or something near the plug to the CTS, seemed like it could put stress on the wiring. Is there a way to remove the plug and test just the wiring, and just the sensor?
This, combined with my recent accident which is also on my list to fix (if Dan Stern ever completes my order so I can install my e-codes) and I am feeling pretty unlucky.
Thanks for listening,
Ryan
