Took a long trip this morning and low and behold, the shuddering and shaking came back, the blinking check engine light and hold light. Used my new OBD II and it says I have a multiple cylinder misfire or a P0300. I did wires, I did spark plug, I did ignition coil pack, what can this possibly be? Frustrated...:mad:
What Causes a P0300 Code?
- Low Fuel Pressure
- Vacuum Leak
- EGR system malfunction
- Internal Engine Problems (such as low compression)
Less Common Causes
- Faulty Coil
- Faulty Spark Plugs and/or Wires
- Camshaft or Crankshaft sensors
- Ignition module
- Computer

Yes, Big Holes in the hose, in the small park of the kinks, 3 big ones, I ordered one on ebay for 18.99.Quote:

Trying to get the cover off the air filter housing was not good. One side was broke. The other, well lets say the screw would turn but not budge. So Guess what happened....??? Yep, that broke as well so we took out the whole housing unit and duct taped it together (see Pictures)... Ok so here is the weird part. For some reason, now, I don't have to press hard on the pedal to get power. It went to 55 in no time and not a single skip, and btw, it was skipping like crazy to my uncles garage. So a somewhat happy ending. I have a hose coming and monday I will go to a U-Pull -It place and get a new (used) air filter housing unit.Attachment 9176Attachment 9177
yup, there's Definitely Air Leaks in your Induction system, at least the Duct Tape will keep you on the road (and the PCM Happy) until you replace the air box and intake pipe.Quote:

Good to hear you may have found your gremlin.
The air intake tube will eventually fail on any Asian car that uses that type of tube. I had the same thing happen on my old Toyota, but the malfunction wasn't quite so dramatic. After 10 or 15 years it is bound to split just from its age. Nothing lasts forever - especially plastic and rubber parts under the hood.Quote:

Same thing happened to me yesterday. P0300 and P0700. Changed plugs and wires and I was off.
