Hi all,

Here comes a bunch of problems again.

Ever since I replaced the O2 sensor, my car was put into limp mode. I sprayed some MAF sensor cleaner into my MAF sensor and it ran good for another 2 weeks.

Now my car starts up with the limp mode again. I tried sprayed MAF sensor cleaner again and no luck. Unplug my battery for 15 mins and tap the brake pedal couple times to reset the ecu and still no luck.

Today after driving for 15 mins, I was not in limp mode anymore but the car still hesitate to accelerate and black smokes coming out from the exhaust. My friend checked my spark plugs and they have carbon built up on the tip so my car is running rich I guess. i checked the surrounding of the fuel injectors and they don't seem to have any leak. When I open the gas cap and I feel the pressure coming out.

What can cause the problem? I googled it and vacuum line, fpr, tps, injector leaks, and knock sensor can cause the problem...
