Weird little deal here. I changed out a very old worn set of NGK 6 for a new set of 5's a few months ago. Replaced the cap,rotor and wires at the same time cleaned the TB etc. My usual Spring tune up. When I did the clutch I had the distributor out and cleaned it up pretty good and it seem to be ok not to worn but original.
Since then cars idle and off idle response has really been bad. I went back to adding 2 gallons of gas to my e85 tank but it has not really made any difference in running. It also appears that the AC idle boost has quit again or the idle loaded is so bad it cant compensate for the load.
I guess I am a little baffled that one heat range different plug would make it run so poorly.
The old plugs were way way worn. I let them go about 3 years. Total bitch getting them out which is another story..Gaps were about .060"
Only other odd thing is warm starting sometime the started kicks back real bad like the car is under compression some how. its a rebuild a few years old so it could be just going bad hot. But sometimes I suspect one injector maybe leaking. there RC engineering 250cc I have had quite a few years. I dont think they are rated for e85 at all. MPG is same as last year running about 24 mpg with E85.
