Hello fellas, I'm going nuts, this car is making me crazy. It does not want to run properly... to be more specific, when it's cold it doesnt GO when you press the gas, acts like it wants to die, hesitates horribly. ARRG!!! I need assistance! I'm to the point where I don't want to dump anymore money into it unless it fixes it! To give some background I have had this since it had 33,000 miles on it, it now has 140,000. I need a someone to point me in the right direction. I have replaced a bunch of stuff trying to narrow the search but so far unsuccessful. This is what I have done: Cleaned MAF Cleaned IAC Cleaned EGR The three above all work properly. I believe, let me know if you think otherwise. I have replaced: All 8 Spark Plugs with Autolite Double Platinum Plugs (with the correct torque I have had issues with this) Replaced all 8 coil Packs Seafoamed it Throttle Position sensor Replaced All 4 Oxygen Sensors with new NGK's All of the things I have replaced have improved performance but the issue is still there. I have had no LIGHT EVER it just runs like crap when its cold. Could it be a DPFE Sensor?? Please Help!!!!!!!!!!!
