Hi Guys, my car started acting up at low rpm this week. Today I drove less than a mile with the car starting to break down. It finally died on my driveway. I eventually got thee car restarted and it showed code 42.
Prior to this, the car did not show codes, but still ran poorly at low rpm and could break down without warning. At higher throttle on the open road it was fine.
I have;
changed MAF
coilpack
checked leads and plugs
checked cam sensor
02 sensor
All scantool numbers were god except the code 42 today
I note that when I turn ign on/not running, my FP guage (in car) shows 'Lo' for a moment before coming up to 43, then down to 37/8
I have no idea what is causing the problem.
I spent all of June chasing a high throtle backfire and 'cured' it.
Now I have the inverse problem and am runing out of ideas.
