Wow ok you need some serious help.

OK first your car dose no have a distributor or plug wires for that matter. The only wires you have going to the plug go into the coil pack and they should never be replaced

also bank one is on the passenger side

your misfires are going to come from the Bad o2 sensor in most cases. Add a bad EGT and you are definitely going to have some issues

Lastly it helps when you proof read what you post. If you want people to read and help it only makes it easier for people to help when there is not words substituted for packs of letters in text message form. I know that I am no literary genius but it always helps when things are spelled right and the reader doesn't have to spend time trying to figure out what you are trying to say

Thiswas meant to be helpful not harsh

 

^ no....
very well put... we are here to help....and the more understanding it is the better we can help

Baskin is defintly on the right track. Looks like an O2 sensor is out

 

no no ur not bein harsh at all sorry it was late and i had just came from a wedding at that pint, anyways thanks alot so i should replace the O2 sensor and the passenger side EGT sensor?

 

point*

 

You really need to replace both as they work together to adjust the fuel. The EGT is the most important but the car will misfire and run rough unless you change the 02 sensor

I know that the EGT sensor is expensive.... but Vast has 02's for 100 each that is 1/2 what the dealer charges. Check them out they usually beat most people's prices so ask them about the EGT as well

But all in all you really need to replace both

 

thanks alot of the info man i appreciate it now all i need to do is raise the money to get the sensors lol

 

EGT sensors are not fun. neither is an 02. both will kill performance. Just get them ASAP.

Did the car blow black smoke at all?

 

no never did, i havent driven the car ever since the post its been sittin in my garage but as far as i kno its never spit out black smoke

 

Shoot for the 02 first, but both sensors are not difficult to replace, but be careful not to pull threads out, and take care not to damage the head of the EGT when replacing it.
