Recently, as i was driving home, i felt my car a little sluggish and started jerking. As i was pulling up my inclined driveway, it lost complete power and stalled on me. It would not turn back on. So i waited until next day and it started, but would bog down as i pressed gas. So automatically i though MAF right? Well, i checked codes, and sure enough, it gave me Knock sensor and MAF code. I bought a used MAF but decided to install that intake mod that was posted on here using MX-6 V6 short ram (looks, and fits reall good by the way). Anyways, i needed to make the MAF wiring shorter, so i made the mistake and didnt disconnect the battery. So i cut all 3 at the same time, and it shorted something out. Well, i connected all wires back correctly, and my car cranks but won't start. I checked the codes and only gave me Knock sensor code (which i still don't know why it keeps giving me this code after i replaced it twice). The computer still works because it sends signal for troubleshooting codes and injectors pulse. Do you think i burnt out the wires and need to replace them? Any suggestions would be helpful. Thanks.

I checked all of the fuses and they were fine. i found the starting problem. After much diagnostics, turns out that when i changed the fuel filter, the hoses got crossed. And also, the spark plugs were fouled from too much drowning them. Engine cranks like a match and engine sounds like it has mad torque. But when i drive, it lacks power, like gasping for air or something. One thing i have to point out is that the car has been sitting for ten years and it has the stock exhaust. some old school gold plated dual tips exhaust. lol. do you think that the catalytic converter or exhaust are getting clogged? thanks
