Houston We Have A Problem Please Help
Houston We Have A Problem Please Help Ok This Is The Last Thing That Is Wrong With The Car. I Changes Every Sensor In The Car. Including Plugs And Wires. When I Drive My Car It Hesitates And Sputters While Drive And When I Give It Some Gas It Tries To Clear Out And Then It Does And Then It Turns On And There It Is Full Power Again. I Changed The 02 Sensors Again Thinking I Have Some Defaulted Ones And New 02 Extensions What Else Can Be My Problem
Well I after I cleaned the iac,maf and tb before I started the car I noticed that the live wire on the battery was very loose, so really it could have been any of that. It only took maybe 1 1/2 hour to take everything off and clean it and let it dry and then put it all back on. But easiest first id check the battery cable if tight maybe clean the parts, once you take them off, if they've never been cleaned, they are very dirty at least mine were.... But I was having the same exact problem that sounds like you are having. my rpm would also jump to 3500 for an instant at idle, that why I thought it was the iac. hopefully this fixes your problem as it did with mine.

there will probably be black junk on the iac and in the hole on the throttle body, thats why I just took the tb off and cleaned it with tb cleaner, there was alot of that black junk around the butterfly on both sides

Check the back of the intake and make sure the little vac line is plug up. A quick check is turn on your AC and make sure it blows in the vents. Also check your fuel injectors make sure the wire are tight. Then check the fuel pressure and coil packs. Sounds like your geting un meterd air some where also. Are you sure you dont have a bad valve spiring or bent push rod? Oh and that little evap thing on the other side of the intake make sure its plug in and not crack.
Are you sure you're reading bank one right? Sounds like bank 2 is dead, which would force entirely too much fuel, causing the bank one to go through the roof.
And it would cause the symptoms you describe.
I know you said you replaced the 02s and extensions, but you could have a burned wire or something.
What are you using to scan? you may want to unplug the 02s and see if they dont go to 440mv or so. If one doesnt, you've got a wire shorted to ground.
