2004 Suzuki Forenza HELP!!!!! Sign In

I have a 2004 Suzuki Forenza. A brief history of what I have been dealing with. Back in December I had my radiator replaced by my mechanic. He had mentioned to me that my car was misfiring. So instead of having him diagnose the problem, I figured I could deal with it on my own. At first the car would jerk back and fourth when I would drive around 60-65. Then the car started losing power. I first changed the plugs and wires and the car was still running bad. I started looking online for other problems. I then replaced the ignition coil and that seemed to fix the problem for about 2 weeks. Then the car started running the same way again (jerking and loss of power). I purchased the coil online and paid $30.00 for it. I then read that cheap coils are the wrong thing to buy so I went to my auto parts store and bought a $120.00 ignition coil hoping that, that was the problem and it wasn't. I then changed the throttle position sensor and that didn't fix the problem. I then took my car back to my mechanic and he said the problem was a clogged catalytic converter. He had taken off the o2 sensor so my car would run better but it would be very loud. So I ordered a catalytic converter online and got someone to install it for me. I put the o2 sensor back on and went for a test drive and like usual my car had no power. Like I would be in 5th gear on the freeway barely going 50 mph. My cars check engine light came on and I took my code reader to it and it said po300 code random misfire. I took the o2 sensor off again and power was restored with the loud sound again. The po300 code always seems to go away with the o2 sensor off. When I put it back on the po300 code comes back on. So I heard that I talked to Scotty Kilmer online (he does a lot of troubleshooting videos on youtube) and he said that I could have a clogged muffler and I should get a pressure test done on the muffler and maybe have the muffler replaced. Well I went to my local muffler shop and he said that a muffler can't get clogged and that the problem is probably some chip in the computer. I wasn't sure about that answer he gave me. So I kept reading online about these issues and decided to replace my o2 sensor. I did that yesterday and drove on the freeway only to experience the same problem every time I put the o2 sensor back on. Lack of power and the po300 code came back on. So I took the o2 sensor off again so I can drive my car. I don't have much money and that is why I've been driving my car like it is. After changing the plugs, wires, checking for vacuum leaks, TPS sensor, cat, and o2 sensor. I am running out of ideas. Any ideas of what else it could be? Please help me. Thank you.

"So instead of having him diagnose the problem, I figured I could deal with it on my own."


That was mistake #1. Scotty Kilmer! Get real, that's entertainment for the gullible. You've replaced enough stuff and spent enough on items that were not the problem with wild guesses without diagnosing anything now you'll confuse the your first chance at just diagnosing it and fix what's wrong.


Why did you replace the radiator? No doubt that was the beginning and source of your problems with lack of coolant and overheating so let the first guy diagnose it,

Scotty Kilmer??????

Don't get me going on that idiot. He is a complete moron.

You could have had this professionally diagnosed 10 times over with the money you have wasted throwing part at it.
