[QUOTE=svx_commuter;569831■ Change the o-ring on the fuel injectors. On the old engines they are hard and leak.
The o-rings on the fuel injectors are old and stiff and do not seal well. Gas can leak around the injector body. Ah this is just a theory right now. I have the o-rings but have not pulled the old ones out yet. On a hot day the O2 was reading very rich. These o-rings get a lot of heat from the engine and I think will only last more than four years. Gosh I hope they are Viton.
Peace,

John,
I think that's an excellent theory. I'd be very interested in hearing the results. If the o-rings are an OEM item could you share the part no's or size spec with us?
Glenn
