When I try to fill my tank with gas, it keeps stopping every few dollars. I know the issue involves the fact that the air won't be allowed in or to vent, but I need to know whether it is the solenoid valve or air canister. Can anyone tell me which one it could be?

Thought 4wd was on all the time can't find problem with Abe and 4wd service lights on any problem to keep driving

Vehicle shifts to 2nd at 4 RPM. I had a diagnostic done that showed some codes on the transmission but they weren't positive what it was and had me do a full tune up to see if it took care of the problem. Had it done but no change. Had another diagnostic done at an auto store and got codes for ERG system fault with probable causes of sensor, valve, and so on. Somebody suggested replacing filter and fluid but I'm wondering if it's worth it to continue to spend money on all these smaller things if I end up having to replace the transmission if none of these work. Not sure what to do and don't understand most of this stuff.

can replacing an oxygen sensor cause an oil leak

My throttle light is visible on my dashboard. What is an estimate of a "throttle" repair? The jeep's gears are shifting slower. Difficulty gaining speed or momentum.

My key was bent and would only start the vehicle if it was inserted into the ignition with the bent part facing up. I drove the vehicle like this for the last couple of years with now problems, except that no one else could seem to get it to start, but me. Recently, the vehicle would sporadically not turn over. All the lights come one, but the engine will not even attempt to turn over. I had the key bent back straight and this seemed to work for a short time. Now it will not start at all. Do I need the ignition lock cylinder replaced?

It runs at about 1700 to 2000 rpms. Appears to take a little longer to shift.

this was after being driven over 5 to 10 miles 3.0 engine

if the engine is cold, it will not stall. Once the engine gets warmed up the idle will go way down and it will stall when you come to a stop. It also smells like gas when it stalls. It usually starts up, but today when the key was in accessory position, it sounded like it was trying to start, but didn't. I turned the key off, and tried again, and it started.

normal braking conditions. Also ABS Brake and Swerve signs coming on intermitantly.

I just purchased a Mercury 2006 Mariner SUV not even a week ago. Just yesterday in driving home the check engine light comes on and system states check emissions system. What does this mean? The was purchased ASIS so can't go back to the dealer to get any help. The car came with no owners manuel so I need to look everything up on the internet.

Just not cool

I was driving down the highway and the battery light came up. i restarted my car and it went off and i drove again and it went back on. Why does it keep going on and off. I drove home and it stayed on.
