My car when not heated first thing in the morning does not work properly...
When I turn my car on for the first time in the day it tries to turn itself off when I start driving it. It is like it has trouble with a cylinder or something. I have taken it to the shop 3 times. Every time the computer shows a cylinder fault. They have already changed spark plugs and solenoids and the car works fine for 2 weeks, then it goes back to the same problem. The only way to get around the problem is to let the car warm up for a while when I turn it on for the first time every day but still I do not feel the car has the same power as before this problem began.
It could be a PCM problem, or it could also be a blown head gasket. What year is the vehicle? Did they change the ignition coil? You say they changed "solenoids" but I'm not sure what you mean in this context.
