Subaru Problems? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** check engine light on?
was the throttle position sensor part of the throttlebody that you replaced?
it should have come on the throttlebody assembly
ok thank you
well the cruise control is cable operated i believe and is attached to the throttle linkage, which can get stuck and hold the throttle open on occasions....
no it can not engage itself. it is a throttle problem possibly caused by a sticking cruise control cable. even if its not engaged. disconnect the cruise control cable from the throttle linkage and see if that cures it.
please let me know how it turns out. then we can take it from there
please dont forget to rate my service....thanks
Sorry to hear you're still having problem. allow me to get home from my shop and get back to you in a bit. thanks
black exhaust smoke can be caused by one or more leaky fuel injectors, too much fuel pressure (sticking fuel pressure regulator), a faulty MAF sensor or Oxygen sensor, or a engine computer fault. the black puff of smoke is rom the computer dumping too much fuel into the system because it think the car is running lean(not enough airflow) I would suggest looking at your air filter to make sure its clean, cleaning the mass airflow sensor also would be a good idea. maybe pull the vacuum hose off of the fuel pressure regulator to make sure no fuel is present on it.
I contacted Subaru about your acceleration issue and its a chronic problem with the foresters that no one has figured out. They have a few successful cases of reprogramming the computer and a couple more of replacing the computer. That seems to be what the problem is. But there is not one thing that they pinpointed to be the definitive culprit.
