O2's, coolant temp, air intake temp, and the spout connector (timing). You all need to do yourself a favor and not throw parts at a problem. Take a systematic approach to the problem and go over the basics first. Air, Fuel, and Spark. If they are all there, as they should be, move on and check other things. If you don't have a code for a bad MAF, why change it? If there is no problem with the TB and TPS sensor and it was set up correctly, why bother with it? If a car is running way lean on a smog machine (basically testing the A/F ratio) what's that tell you? It's got something to do with the timing. Have you checked the balancer to make sure the ring hasn't spun? Sure sounds like the timing is sitting at about 5-6* BTDC. Hense the pop through the intake and lean condition! -------------------- 1965 Shelby Cobra 1993 Cobra 2012 F150 Raptor 2020 GT500 Posts: 6523 | From: Orlando FL/Redding CA | Registered: Mar 2002  |  : Spitfiremk24 ¯ Member # 5698 posted                              this guy should get paid for posting here... -------------------- 04 GT Posts: 218 | From: East Bay | Registered: May 2005  |  : stangless ¯ Member # 1414 posted                              yeah.. everytime i have a question and post something.. i pray and hope that jonhb sees it and has a chance to reply.. -------------------- =( Posts: 4634 | From: bay | Registered: Jun 2002  |  : TrickRacer50 ¯ Member # 6345 posted                                 exhaust leaks can cause all kinds of surging problems and such, especially around the collectors. Make sure your plugs are in the correct firing order. If you buy new O2 sensors, get the kit from FordRacing at Summit. It is cheap, because you get new O2 sensors and a bunch of relays and other vital sensors that can cause problems. This kit (below) is cheaper than just buying 2 new O2 sensors.
