Hey guys I'm new here, I just nought my first Cadillac, a 98 deville 4 door with 102, 000 miles.
I'm looking for info on if there are some recommended performance upgrades and where to find them. Also is it time to replace plugs? Wires? Coil packs? And if so which ones? I've commuted this car to work for three or four days and some mixed driving, getting 23 mpg. Seems like it rides nice but there is a noticabnoticeable light dimming when I hit the brakes. Possible voltage regulator? Or maybe a bad ground?
Was definitely looking for a programmer if they exist and possibly intake? Exhaust? Am I being crazy to look for that stuff?
Thanks for any info guys!
