Hey everyone.
so my 2003 P5 has a pretty bad misfire i know i was throwing the p0300 code along with many others. i finally got around to replacing the upstream O2 sensor but i feel like i took too long. the car was drive-able for a while but it sputters badly at idle it sputters really bad when i put my foot down on the gas. after i replaced the upstream it started smoking from the pre-cat area which i thought was weird. although the car now sputters less, it still does it at idle from time to time and almost everytime i put my foot down on the gas.
im thinking of changing the Coil packs, the down stream, and if it doesnt get better, the MAF then the pre cat it self. if none if this fixes it im honestly done with the car be cause ive dumped a lot of money into it already with just repairs. do you guys have any tips on what i should change/ look at? or any order i should change these parts in ? because , for example, i dont want to change all these parts just to find out that the pre cat was the problem and i could have changed that to start with.
Also does anyone have experience with or know about the quality of the Evan Fischer Front Catalytic Converter because it seems pretty cheap and usually cats are more expensive than that. i just dont want to pass up a product that will work beaus its cheap. if i could save money on this it would be great.
