replaced plugs and wires and code still flashing

Hey guys, I just got done replacing my plugs/wires and I'm still getting a p0300 code. Any suggestions?

Did you route them the same way they were before? What kind of plugs?

Re: replaced plugs and wires and code still flashing

Yes, they are tr6s gapped at .035. It runs better, but it's still misfiring

Cross-firing is what came to mind when you said you had misfire and changed the wires. Do you have a power adder of some sort? I thought the plug gap is supposed to be 0.060".

I think it's the coils.
Some of french guy have had this same problem, me too

Re: replaced plugs and wires and code still flashing

I just replaced the coils not too long ago. I may just go ahead and take it to a shop to have them diagnose it and then see what I will do from there. Btw, what part of france are you from? I may be going to the toulouse business school for 2 months next year

Toulouse is a good city on south (good weather). I live on north of france (900km of toulouse).

Check all your plug connections again and see if they are on well. If its missing only when the car warms up, id say coils...

Yea I'm not sure, it doesn't miss when I first start it, but it does when I actually start running it. I'm just gonna take it in and eat the cost. I probably have arcing somewhere sigh

Well it just keeps getting better!!! I was leavign work today (my gas guage hasn't worked in over a year, but I usually keep it at half a tank at least). I had 126 miles on the clock since I last filled up. I got about 2 miles away form work and ran out of gas. No idea why and the radio is breaking up and i also hear a buzzing noise inside the car. This is turning out to be a nightmare quickly :( I work 22 miles away 1 way, so I need to fix thsi ASAP! I guess it's off to the shop tomorrow since I'm off

Hey man I had a p0300 codea few years ago that I couldn't figure out to save my life. I changed everything in fuel and ignition system and still had it. Finally found it after thousands of doallrs spent was upper. intake gasket leak. This all happened due to bad gas.

Re: replaced plugs and wires and code still flashing

Ok here's the update:

I am having the car checked out at a local shop right now. It seems I have a cylindar 1 and 4 misfire, so I'm thinking it's my coil pack. That should take care of the misfire. We are trying to figure out why I'm running so rich now. I'll update with mroe info soon
