My engine is the 3vze and it usually runs like a champ. I have an intake and exhaust so it breaths well. When the problem started I had that plug wire wire fall off. After this I found the ground wire from the block to the fenderwell . There is also that condenser that is connected to the same bolt on the block. The other side of the condenser disappears into the wiring harness. Dose anyone know what that condenser is for ? And can it cause code 43? I think code 52 is going off because it is running ruff due to code 43. Once vehicle is started I Have no check engine light. After I start driving or engine is under load such as reving. Light will come on. Starts to run really bad. Seems like it can't get fule ratio and spark together. Thats what leads me to think that condenser could be to something in the computer system. Could that burnt wire have affected the condenser
