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

I am still leaning on your cht or valve adjustment..
but to test the aar, first take an observation notice. does your idle speed drop a little after it is warmed up say 15 minutes idle or longer.. or you can take it out and apply voltage and watched the valve inside? if not then the aar is stuck... i would not worry about the cold start valve yet, but you can pull it out and turn the key without staring it a few times and see if it is leaking.. the cold start valve does not even operate (or at least not supposed too) unless your in freezing tempature weather as stated above.. it get the signal from your ts1... your description suggest symptoms of warm start over enrichment without the warm start over, cold cold start right? not warm cold start? djet trouble shooting tips and guide analysis ... read link below http://members.rennlist.com/pbanders/DJetParts.htm |
