My first time so bare with me!
Working on a 98 accord v6. Car sat for a year due to a no start problem. Thats what I was told. Towed home spent ten min charging batt and checking fuel and spark. Everything check out so used a little starting fuild and car started up sounded surprisingly good other then a instant idle surge from about 1200 to 1800. No check engine lights! Read a few forums and the iacv seemed to be the best place to start. So replaced it and cleaned throttle body and replaced gaskets. Put all back together and at first start up seem to run fine with a little higher idle then normal but after a min it began to surge again. The surging last about a min and ran at high idle unless I give it gas then it surges for about a min again. I ended unplugging the map to see what would happen and the idle dropped and seem to run smooth with no surge. So I figure I would put a new map sensor in. After I did had same issue! Started up fine with about a 1200 idle once it warmed up it surge for about a min then stop at a high idle. I unplug the new map sensor and the idle dropped and smoothed out but of course the engine light comes on. I check for vac leaks, cleaned egr ports, did a tune up but still have the idle surge a nd high idle. Read a few threads that honda's need to relearn the idle and some have idle adjustments but not sure is this year does thatand not sure it will take care of the surging! Any help would be great!
have the same problem?
