Sounds interesting. I think what he was getting at here is to fool your air temp sensor into sending better air temp data to the ECU, if in fact the air temp sensor is bad. That sensor is just a variable resistor that changes resistance with temp. The resistance generally drops as the temp rises. There is a figure in the FI document on Toby's site that shows the temp-resistance curve for both temp sensors. Cold, the resistance is around 300 to 500 ohm for the air temp sensor. Hot, resistance should approach 100 ohm. You can measure this easily. > all kinds of things from valve adj., timing, voltage regulator. . . the > works.

If you tweeked the sensor, all bets are off on getting it right again unless you can get it back to the factory setting. Unless you really know what you're doing, I think most would agree that it is best not to monkey with the pressure sensor -- ever. If you tweeked the regulator, I'd get it back down to 28psi. Are your trigger contacts clean and uncontaminated? Fuel filter clean? Gas tank clean? Bad grounds? Double check the ignition components (points, plugs, wires, timing, etc.) are all adjusted right. -Mark ------------------------------------------------------------------- Too much?
