running issues... HELP!
I searched the forums last night for about 2 hours before finally giving up, so now I need to ask and I really hope someone can help. I have a 2001 v92c, mileage is anywhere between 8500 and 25000 (used guage off ebay says 25000, old gauge 8500). I assume it hasn't been ran much in the last few years as it was a prior salvage. (some one did a crappie flop into some weeds is what I gather). So, I've done my work, changed the oil, filter, air filter. Took her out for the last couple days with fresh gas and sea foam to help. here are the results: Starts fine, and after some minor adjustments idles fine. Gets warmed up. Shifts like it should. Rolling in town at around 1800-2300 rpm and it surges, but I can't tell if it's starving or loading up. Get it on highway at 55-70 mph and it runs like a champ. Exhaust doesn't smell rich or lean. come back into town, down shift, rolling about 25-35 mph at 1800-2300 again and it starts to surge, kind of feels like it wants to die. Has progressively gotten worse. I'm in the process of removing tank (guy who did the work removed the quick disconnect so I need to get a couple small vise grips to clamp the hoses). I plan on cleaning the throttle body, and replace the plugs, but I want to know if there are any other things I need/should look at or replace while I'm in there. I'm no stranger to turning a wrench, but I am on the Vic as my last one ran fine. I don't have any manuals, so if someone has seen a thread like this with pics, or has some pics they can attach or link me to that would be great. Thanks in advance.
