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

Check your cold start valve - that's what it usually turned out to be on my 73 2L when giving the cold running symptoms you note.
Here's a link to the part if you need it, but shop around as the price can vary: http://www.automotion.com/product.asp?pf_i...mp;dept_id=4678 |

The CHT resistance as more to do with actual communication to the ECU on engine warmth ect.. Possible to long between or since valve adjustment time.. |
