CX 2.5 Starts but will not idle

Unread post by Hydraulique »

I have a 1985, Series one CX Prestige with injected 2.5 liter engine. It had been sitting for about 5 months and now starts up only if I tap the gas but runs rough, and will not idle even when run to temp. Most recently It backfired once. I have checked the intake path and all seems tight. Plugs all look ok and seem to be getting spark. Compression is great at 150. New gas in tank and I drained tank to be sure all was clear. I ran some techron in the gas to see if I could clear a bad injector- no luck. I did install a new battery before this round and I now see one yellow wire and spade connector that is not terminated on the left side near the battery. No obvious destination. Anyone encounter this situation before? Thanks!

Not sure what you mean by 'tap the gas' ? :)
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!
