The car seems to have a high carbon build up. Jon, the spark plugs are brand new I could tell when I pulled them but they were black as can be (carbon build up). There's a lot of carbon deposits coming out of the exhaust, turning the bottom end of the bumper black and leaving a streak of carbon on the driveway. The spark plugs were gapped at around .032 which is fine according to sources I found. The spark plugs I put in were the same kind I took out but I gapped mine at .028 which is according to the manufacturer. I did keep the ones you put in Jon. I'm going to clean them and re-use them. I went ahead and cleaned out the throttlebody it was nasty and the plate was slightly opened (could be the reason why it idle high). I sprayed the intake cleaner and started up the car took if for a drive... smoke came out of the exhaust for about 3-5 minutes and hesitation slowly went away. The smoke went away car felt much better with minor hesitation unlike before. I'm thinking I need to run a FISC (Fuel Injection System Cleaner) which is directly flowed into the line of the pcv valve to clean out that heavy carbon build up. Also buy a bottle to put into the gas tank. Thats the only explanation I have for it... carbon build up. Jon, I am aware of the knock sensor wire being cut I have not had a chance to replace it with the new one you bought and gave me. But hopefully I can change it tomorrow ( I took off from work) or this weekend.
