Having problems with your Cars & Trucks ?

P0442 Check engine light came on. checked codes. it reads p0442 evaporated emissions leak (small). I bought a new gas cap and have been screwing it on with three clicks. I checked all around full lines, but can't find a leak. My truck also has to be turned over the second time to start since the check engine light has come on. Wondering if there is a way to narrow down the problem?

Answers :

If the check engine light is coming on i would take it to a shop and let them put it on a computer that would give the correct problem. A simple code scan does not work most of the time and the reason for that is if one sensor is bad it can make scan read other sensors bad. hard to start could be sensor or simply a good tuneup is in order. easyest solution is take it to the shop. in the long run it will cost less.

My check engine light came on. The dealership said "filler neck leaking causing evaporative leak." The gas cap also says "loose cap will turn on check engine light." Would like to try a new gas cap but do not know how to turn off check engine light to see if that is the problem.

Our 2003 Passat had a check engine light, and it turned out the coolant level was low. We brought it in to the dealership to check for a leak, and they couldn't find a coolant leak anywhere, even though the coolant level was below min. They did, however, find that the water pump wasn't functioning properly and needed to be replaced, along with the thermostat. Before we drop the $750, I'm wondering if we should get a second opinion...any info would help.


The answer is a definite yes to the second opinion. I don't know how they mean when they say the pump is not functioning properly. It may be leaking out of the waterpump seal in which case you have an explanation for your water leak. That would be a ... 2003 Volkswagen Passat

2005 Dodge Durango 5.7 HEMI I was parked with the engine running and the abs light popped on, then the brake light came on and then a couple seconds later, the air bag light pops up and finally the check engine light decided to pop on too. I shut the engine off and when I turned it back on, everything except the check engine light was gone. Any help from anyone would be great. I have 42,000 miles and there are no freebies at the dealership.

My vehicle would not start this morning. After turning the key in the ignition, the engine turns over and all the lights work, but then the car shuts off. No check engine light is on. I am thinking that it is the fuel pump. It started some time later and seemed to be leaking oil out of the oil filter. Oil had been changed a week ago. Tightened oil filter (it about 1/4 turn) no longer seems to be leaking oil. Still worried about the shutting off. Recommendations?

Sounds like the engine is going into limp mode for whatever reason. You need to have the ECU scanned with an OBD2 scan tool in order to make an intelligent diagnosis of the problem. This tool will retrieve the code that has been set by the ECU. That ... 2003 Chrysler Sebring

I have 95,000 miles on my Grand Mercury LS car. Tonight my engine light came on with 1/2 tank of gas. I checked the gas cap (appeared okay - full tank fill up yesterday before my 175 mile road trip - no problems experienced). Per the owner's manual I turned the car on 4 normal times and the check engine light is still on. On the last attempt, the dash blacked out momentarily after about 10 seconds and the engine had a heavy sigh and resumed normal idle. No previous problems before (full ser
