Anyone have any suggestions? I mentioned last week that I was having the high speed accelleration issues - didn't sound like a transmission issue, but more of a fuel delivery issue, possibly. Anyhow, even though it was still running ok, I decided to use the last couple days before the big "winter" sets in and do a tuneup since I picked up this car a few weeks ago and didn't know much about the history on it (the usual low mileage, original everything syndrome). Here's how it went... Removed the two allen bolts and was able to squeeze out the distributor cap to replace the rotor/cap with Bosch replacements. I also replaced the wires, spark plugs with Platinum +4's, and went ahead and put in a new Bosch fuel filter, since a few people mentioned that I may have something in there blocking my fuel flow for the high speed accel. issue. I go to start up the car after all of this, and it starts up right away and sounds ok. I go to drive it, and what a mess - the car now has almost a rhythmic vibration to it when you hit the gas. I had a older British car that once had this same feeling when it would foul up a plug or two...just didn't have that smooth "purr" like it used to. So, with that in mind, I took it back into the garage, pulled the plugs and took another look...all the plugs looked equal - charred black except for the top of the +4 plug which was white. Seeing it was all the same, I though I'd try putting the old plugs in..just to see if it made a difference. Now that quick pulsating vibration is gone, but it doesn't accerate at all...it's like the high speed acceleration thing, but now at EVERY speed. I give it gas...and I can barely get it up to 25mph in the neighborhood. I can sense the different gears engaging, so I don't think it's the "starting in 2nd gear" syndrome... before it started running really bad, at least it would go quicker than 25mph. I checked around for any vacuum lines or anything that may have been disconnected, but didn't see any...but admittedly, it's not the easiest area of the car to check around, since you can't see half of what you're working with, in the first place!. Two days ago before I did anything, it was going up to 80 without a hitch! Any thoughts? (other than "tough luck!" ? :) ) I'm wondering if there's a possibility the cap wasn't put on quite right, etc.. something dumb...but in that case, I'd be surprised it would be running at all. It sounds good just sitting in the driveway idling.. but perhaps I did knock something out on the fuel system side of things when I was pulling up on the fuel distributor/fuel mixture/etc housing. Any suggestions are appreciated! Pete
