Jeremiah, Don't worry, I have no intention of replacing expensive fuel components without testing them first. I wanted to see what possible causes were to help with my troubleshooting this. After reading a few posts, I went over the vacuum connections and checked the power connection on the warm-up regulator. While I cleaned the power connector in the past, I didn't do a good job because upon closer inspection the connections were very corroded. Now the car cold starts perfectly! I won't know if it's completely fixed until the I let the car sit for a few more days and try starting it again. However, my hot start is still not working too well. So I've ordered the Bosch fuel tester. I'm curious as to what it's going to show. I've already replaced all the major components that typically cause hot starts issues (including the O-rings in the PPR). If the fuel pressures check out, it looks like I may need to get the mixture slightly adjusted. Thanks for the tips, Chris VIN 4099 At 11:41 PM 9/25/2005 -0700, you wrote: >Ok.
