soo lately just this weekend actuaclly, weve gotten alot of rain.
my car acts real funny. the idle acts wierd, kinda surges a little bit, and when i go to hit the gas, it jerks really hard like its hitting fuel cut or soething. while im crusing, it will randomly fall on its face.
its wierd thought because it doesnt do it all the time. itr did it today at lunch, and after work. i unpulled the map sensor and tps, then reset the ecu and that seemed to help for a while. but i have a feeling its gunna do it again.

the car needs an o2 sensore i already know trhat and have one ready to go in. but its one of those universal ones and i am terrible with wiring soo im kinda nervous to put it in..
would this maybe be the problem?

btw the car is an eg hatch with b18b1.

thanks!

 

What CEL codes are thrown?

How old are the plugs, wires, cap, and rotor?
