Last time I drove the Red I noticed that the oil pressure was "dancing" a bit so I went to Rock Auto and Amazon to price out sending units. Standard was about $50.00 each at both places so I went to Ebay and bought 2 for the combined price of $40.00 delivered. I already had one but now I have an extra one for each of my cars.
On another note and a bit of a rant. I came here and talked about buying another Delco ignition conversion plate and how important it is to have extra tested ignition modules so one can tell if that is the problem [and it is the most common problem] and yet no one contacted me about buying it. Guys why do you not invest in your car and have a few common parts around to keep your cars running? What I see when the problem starts is new parts are bought to throw at it, get frustrated and sell the car. When an extra set of plug wires, plugs, mass air flow sensor, oxygen sensor, Delco coil pack and ignition module takes care of about 90% of the cars issues.
I run thousands of miles a year and I'll bet in the 15 years of combined ownership of all my cars about 300,000 miles on top of the 100,000 miles the cars already had on them not had the down time I have read about here.
End of rant...
