I'm at work, wife's at home, so I may revise the diagnosis once I've had a chance to look at the car.
Was running fine as of yesterday... (90 Beretta 3.1 V6, auto.)
Started running rough this morning, check engine light apparently is flashing, and will gradually increase speed if you take your foot off the gas around 30mph, but takes forever to get up to 30mph because it's running so bad.
I'm going to dump the codes, but that sounds like a vacuum leak of some kind, especially because it "just happened."
I don't think the car even made it into closed loop, sounds like it was running for all of 30 seconds before it started to run like this.
Plugs and wires are a couple years old, probably due, but not horribly old. Air filter was done about 3 months ago.
What about ignition coil failure? Would one of them just fail? (It has the pack of three.) Other than an ohmmeter, is there anyway to test them at home?
