I just purchased an 86 T-Type. I have driven the car all of 1 mile since it arrived on the transport truck on Sunday (waiting for tags, plates and inspection). Yesterday, the car had a bit of a stumble, rough idle and the CEL came on. I checked for codes and got a code #41 (Cam Sensor Circuit Failure). I pulled the car into the garage, shut it off for a minute and tried to restart it. The engine would turn over, but the car would not start. I went inside and cooled off for about 20 minutes and then tried to start the car again. It fired right up and there was no CEL. I let it idle for a couple of minutes and the CEL returned. Again, code #41.
I’ll add that the car would hesitate/stumble during initial acceleration but smooth out after. It also seems to spool quite slowly for being equipped with a Precision 6262 BB and a 10” 3200 converter which (in my research here on turbobuick revealed) is another symptom of a cam sensor related problem.
From my research so far, it appears it could be a bad cap, sensor, etc. I contacted the previous owner and he mentioned he had to replace the cap twice in the past and the sensor once. I figure I will start by replacing the cap which leads me to my first question. Assuming the sensor was installed correctly (previous owner said the car ran fine), is the cap (equipped with an LED light) a simple bolt-on and go replacement? The sensor itself is what’s adjusted, not the cap, correct?
I guess my other question would be:
If a new cap doesn’t fix this problem, where would be the next place to start? Sensor?
Sorry for this being so long. I wanted to be thorough. If you need more information to help diagnose the problem, just let me know.
Thanks,
Ross
