Forgot about the high beam indicator.
A GM Tech 2 would make quick work of figuring out if it's a bad BCM or bad IPC.
Again.....service manual has you connect the Tech 2 and do a IPC display test.
"High Beam Indicator Malfunction
Ignition ON, with a scan tool perform the Display Test for the instrument panel cluster (IPC) and observe the high beam indicator.
⇒ If the high beam indicator illuminates during the test, replace the BCM.
⇒ If the high beam indicator does not illuminate during the test or remains illuminated at all times, replace the IPC."
This is mostly for my own memory. Help is always appreciated but never expected.
To begin, we have already got some new tires, and I learned at that shop that my rear tire cambers -3 degrees, and the front is bent in a bit. But before I get an alignment, I need new struts all around. *smurf* is getting expensive.
Put in Marvel's Mystery Oil to quiet a lifter tick, and so far, it's not doing that much; need to drive more miles with it. ATF was thrown in too so I can save my Marvel's Mystery Oil.
Next week I need to go and get a tune up; basically, need fuel filter and spark set/distributor.
I am missing some underhood relays from the car. Can't tell what they are supposed to be, but I can bet its all three cooling fan relays.
Current Issues (prioritized):
Lifter noise from the engine
Exhaust smelly, and excessive (diagnosed; tune up will fix it)
Wheels unaligned, cambering, and could cause tire damage
Leaks: puddle on the valve train. Obvious gasket issue. Leak in the back end of engine, but isn't worth the lift
oil had never touched the ground, so this isn't too too bad. The oil near the valvetrain is sus though
Climate Control only turns on sometimes. Looking at wires soon but it could be the panel or BCM.
Cruise Control is obsolete. Not switching whatsoever. Fuse, wire, or connector issue? Switch?
ABS brake lock and traction will flicker on and off sometimes. Wire issue for sure.
A/C service light on; may indicate lack of refrigerant or that the relays are out.
Radio disconnected; previous owner wanted to get subs. Little did they know these cars are 50% wire.
Here is what parts Eve, my little devil, needs:
TUNE UP: Fuel filter, distributor cap + rotor, spark plugs + wires. quoted at about $400
Struts all around and alignment. maybe $500? got a rough joint too
Valve gasket $20
Still gotta figure out if Marvel's or ATF can clean it up more,
Still looking into this one, but I'm hearing every 90s Deville owner should keep a spare.
Radio wire connector
wires need to be connected again and we need to investigate more
That is my comprehensive list for my ADD brain. All this figured out in one week. Bought the car ten days ago and she's made me give nothing but attention to her. Hope it's all worth it!
I have a friend in his 80s with a 81 Eldorado Barritz his mechanic swapped out the computer loosing the memcal chips any chance you might know where I can help him find either the memcals or a salvage computer?
Good morning Mike. I've been searching in the forum about rich cold start. I have a 1993 Cadillac deville 4.9 v8. I've done maintenance. full tune up. Plugs, wires, cap and rotor. New EGR, and new PCV valve. Throttle body cleaned and air intakes (those were bad) checked the timing yesterday (at 24 degrees) don't know why but I'll bring it down. Cold start rough... too much fuel. Runs perfect after warm. Any suggestions about the rich cold start? Any info it would be much appreciated. thank you.
