Hey Folks,
I'l try NOT to be verbose, but I'm a SAAB guy entering into the long awaited DMC realm after 5 years of ownership, but not actually driving the darn car due to combat tours and renovation time.
History: Car purchased from AZ owner while in Iraq 2009. Shipped to Bauerle Automotive and refurbished over the next 4 years and two combat tours. Stage II upgrade, custom (annoyingly loud and catless) exhaust, remote doors and a host of other minor electrical and aesthetic upgrades as well as transmission rebuild. Car had 11,300 and now has 13,000 since I've been driving the crap out of it thanks to my SAAB Viggen being down for maintenance (repairs/upgrades).
1./ The car was driving like the bomb diggity and ALWAYS fired up within 2-3 seconds then one day within a week of taking it out of winter storage I turned it over, hot starting after a Home Depot run, and its run like CRAP ever since. Two weeks now. Starts hard ALWAYS now regardless of hot or cold, but reliably and reluctantly grumbles to life within 10 secs every time (though it sounds like arse). Likes to pause under load in each gear until I've revved it past 2800. Does it less when warm.
- Replaced ignition coil and wires with Pertronix 40kva coil, 8mm blue silicone wires, new K&N filter and "shielded" core wire from core to cap. I thought maybe my coil went and wasn't burning off fuel. This did nothing but allow for the car to start badly quicker. Not sure if that's good or bad as the problem is obviously NOT the ignition system.
- Brand new Bosch fuel injectors on the way and a new accumulator (both on my car are original) because of stuff I've read in these forums in terms of common failures and I pulled injectors 2&3 and they look like poo covered with rust/corrosion. I think the issue is fuel related, but whatever it is, it happened quickly. The car was working brilliantly, then 20 mins later the car just wouldn't run well at ALL and has been that way since.
2./ On the way to work this morning I experienced a sudden and violent uncommanded throttle accelleration shifting between 3rd and 4th gears. I saw 8000 rpm before I tapped the pedal and it decided to go back to idle. It scared the HELL out of me. What was that?? I've read the "sticky" and "sticking" throttle threads because I have idle issues too, but nobody has mentioned this weirdness. Ideas?
3./ Brakes violently vibrate when applied causing steering wheel shake and the car does NOT brake well. I'm assuming this is a warped rotor fault as the rotors are the original 32 year old ones. Ideas? Thinking of new rotors and pads all around.
I have more, but that's enough for now. I have scoured this forum (and the UK one) for days doing research, but I need some ideas on the engine and throttle faults that I have at least. Based on what I've read it could be one thing or another. Argh! I had a 1984 BMW 633, but this DMC-12 is like, arcane compared to that car so I'm a little out of my league here starting out with DIY. I will get it, but I hope you guys can help bend my learning curve a bit. I'm a UH-60 Blackhawk Test Pilot so I have the mechanical know-how and tools, but not the KNOWLEDGE as it relates to this model. Please help as it's been a little embarrassing for me to drive the car the way it performs/sounds: mallet:.
