I have a 2002 honda accord lx 2.3 automatic My car starts and stays running until I give it gas then it stalls. I put in new tps sensor, spark plugs and the rotor and the fuel pump and still no change plus...


Check your engine wires or boots if this is a coil over set up. but i dont think it would cause a complete stall, just a crappy idle unless really bad...

Checking sensor activity would be best with a scan tool. Watch your MASS AIR FLOW SENSOR (MAF) G/S should increase as engine speeds increase. It should not be stuck. Tap this part if it appears in a stuck value it sometimes acts up and can show its self. This part watches air going into the engine. If this is false, the engine cannot meet the demands from you because it is has no idea how much fuel to mix or has a bad idea due to sluggish sensor. G/s @ idle is usually around 4g- 8g depending on most cars.

Also check for typical vacuum leaks and intake hose leaks. if you replaced this many items. My best guess would be check MAF sensor.

Good luck

Engine running rough all of the sudden


Try Maf sensor,(Mass air flow)
Then try tps sensor, (throttle position sensor)

Rough idle while in gear. There are no engine lights on. I replaced the spark plugs 6 months ago and seemed run better. Rough idle came back, so I cleaned out the PCV valve and it helped for the short...


Are your rpm's low when sitting at a stop light and vehicle warmed up? You could check your TPS (Throttle position sensor) or maybe your egr is plugging up, or one of your plugs or wires could have gone bad, maybe the coil on one of the wires is bad. You really need to plug a code reader into the ECU and see if there is a code being thrown. And NO, all codes will not cause the engine light to come on.

Car is rough idling and shaking a little. Replaced plugs, air filter, coil. All made a little better but still not fixed. I looked at my injectors and one was wet and one was dry?? Not sure I'f that's...


Take your car for a compression test to see if there is any vacuum leak causing the engine to run rough. Also, this could be due to a bad MAF sensor or an O2 sensor. If the check engine light is ON, you should better get the codes read.

Bad idle, no takeoff


Was the replacement MAP sensor new original or aftermarket, or used maybe? How is the reading of the O2 sensor? STFT and LTFT at idle and driving? Try testing the EGR or just plug the EGR port and try it if any improvement. It is asking for serious diagnostic work.

Idles okay, runs rough when gas applied


Either a bad MAP sensor, or TPS. What is the code for the check engine light? This will most likely tell you what it is.

1990 Buick Century 3.3L Check Engine Light comes on, stalls.


Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.
