Hi verybody: Any help here is greatly apprecialted. My 74 2.0 studders, hesitates and runs rough 1 min after starting up for about 10 min. It runs ok when warmed up fully, but I think it would run even better warm and cold if this problem was solved. I've checked for the obvious vacume leeks - found none, and I checked the temp head sensor neat # 3 cylinder. When I connected the harness wire to negative batt terminal the car would barely run. I guess the sensor is OK?. Thank you for any help on this, everyone on this site has been really helpful - great site!. Thanks, Joe

Does "cold" mean 15 degrees F outside, or just the engine has not yet been warmed up to regular operating temperature?

QUOTE(ericread @ May 10 2010, 08:54 AM)  Does "cold" mean 15 degrees F outside, or just the engine has not yet been warmed up to regular operating temperature? Eric cold for the engine means ambient tempature( in so. cal. that means about 70 degress in the afternoon), cold for the cold start valve means near freezing ambient tempatures (montana winter ect..)... |
