Hi guys,

I finally had a chance to check out the air intake and coolant temp sensors this evening. The readings were in line with the resistance values posted elsewhere in the forums.

I also re-checked the duty cycle and it was the same as I had set it before (~50%, oscillating) both at idle and at 2500rpm. Vacuum connections and lines checked out ok with the mity-vac.

I swapped out the O2 sensor about a year ago and it appears to still be working according to the multimeter readings. The IACV is functioning and I resoldered the connections in the OVP a year or so ago.

What else could cause such a huge drop in economy? I'd appreciate any ideas on what else I could look into. I'm thinking clogged fuel filter, leaking EHA, injectors, or cold start valve? I'm going to pull the spark plugs tomorrow to see if they have anything to say.

Thanks for any input you might have!
