Hi. I picked up aan 88 Honda Accord LX with just 58k miles on it. Itgenerally looks and runs great.About a few weeks after I got it, it started to idle high when cold. When Istarted it up, it would run around 1.5-2k rpm in park and about 1.3-1.75 inneutral or drive. Generally after it warmed up, it would drop down to .75-1krpm and act normally. It was and still is manageable.I tried removing the air filter housing and got in there with a can of carbspray and sprayed in and around the carb. It did really seem to help forabout 3 weeks. It mostly behaved normally for that time.It has now returned to its former behavior, though not quite as bad. Itrarely get as high as 2k rpm. More like 1.5-1.75. It does seem to takelonger, however, for the idle to settle down to normal?.longer drives andlonger time. I?ve tried revving the engine to 8k rpm for a minute or so andthat seems to help a little bit, but not much. It just seems like it needsto warm up. If I drive it a short distance, park it and then start it again,sometimes it will then idle normally.I?m planning on spraying it out again, maybe using 2 cans this time. Is thissomething I need to be worried about and get it checked out by a mechanicright away? Can it be symptomatic of a more serious problem? I?ve beendoing a lot of research and I love to figure things out for myself and itwould be a fun little project to be able to fix it on my own.Any suggestions? Should I be looking at another possibility other than thecarb? How tough is it to pull out the old carb and put in a rebuilt one?Should I get a new one or rebuilt if I decide to go that route?Thank you in advance!Steve, L.A.
