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

Do an Ohm meter test on your CHT.
Do it when cold, then when hot. You should have low ohms when cold, and high when hot. See Pbanders Djet site on Rennlist for the exact readings your CHT must adhere to in order to function properly. Each year is different so look up your year CHT (ECU dependent) Aside from that, points, plugs, wires, valve adjustment work wonders. Rich |
