Your temp sensors are probably fine, but you should at least verify the cold temp readings. 2500 ohm for the head temp sensor would be about right for room temperature (~70F). At operating temperature, the resistance decreases to about 1000 ohm +/- a couple hundred ohm. Your 940 reading might be a tad low, but it is probably close enough. The air temp sensor should measure about an order of magnitude lower than the head temp sensor (~300 +/- 50 ohm at 70F and ~100 to 150 ohm at temp). Measure that fuel pressure. Do you have a cold-start injector? What kind of fuel economy do you get? -Mark Fuhriman ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
