Runs rough iddling rough even with recent tune up, check engine light on when fuel tank was at 1/4 tank it started flashing. could it be the o2 sensor . runs fine on the inerstate
it acelerates ok but when you are stopped at a light it starts to idle rough and when the gas tank get to a quarter of a tank the check engine light flashes and when you fill it up it stops flashing and the check engine light just stays on. will check the codesit acelerates ok but when you are stopped at a light it starts to idle rough and when the gas tank get to a quarter of a tank the check engine light flashes and when you fill it up it stops flashing and the check engine light just stays on. will check the codes
I had my oil changed, and the also suggested I have a fuel filter installed. Now my car dies repeatedly when starting or idling (at a stop light) or when I am slowing down for a turn, etc. After it runs for a while it is okay - until next start. The engine light came on prior to the engine service. The code was for the thermostat, which was replaced just after the service job. The engine light is still on - now car is running rough and terrible. It was running fine (except thermostat) before all this. What's up?

2001 Mazda MVP: I was having problems with my turning signals and had to return the vehicle three time suntil it was finally fixed but two days later the check engine light came on which it normally does if the gas level is low. But I filled the tank and rove it for a day until light went off but came right back on. Drives fine but when I stop for lights or long periods the engine seems like it's working hard to stay on causing the car to move forward. I don't just want to take it back to the dealer until I know what it might be because of the turning signal situation. I need suggestions to give these guys I see.2001 Mazda MVP: I was having problems with my turning signals and had to return the vehicle three time suntil it was finally fixed but two days later the check engine light came on which it normally does if the gas level is low.

Lets start at the beginning. Did anyone check fuel pressure before and after replacing the pump ? Has anyone checked the fuel pressure regulator and the injector spider ? The 4.3w engine uses a spider with one injector that supplies all 6 cylinders. And it runs at 65psi or more.
The check engine light is because all check engine light codes are caused by components that affect emissions. It's not actually an engine problem, it's a problem with either your O2 sensor, MAF sensor, fuel/air ratio, pyrometer, or exhaust. ______________ gm diagnostic tools
Code P0155, 1155, will get those code's with vacuum leaks, I have seen that many times here at my repair shop, many times customers come in, after they have done a tune-up, as you have, and same problem, check for vacuum leaks, more so on top of engine to the back, by fire wall.
You have 1. A bad injector, which is about to break up and damage your engine or a coil or spark plug wire going bad. Or broke or you have lost compression in that cylinder so first I would do a compression check to see if compression is ok if it is then test the injector and or replace and check for intake leaks around the intake near that cylinder by spraying a small amount of WD 40 around the intake to see if it smoothes out if it does you have an intake leak take it to someone who can do it if your not sure how. and Please rate my answer. thaks Avid101
