ok guys here we go....
after the winter operation of the cyclone intake to gain bottom end torque and turbo spool up....also while under the knife I swapped out the timing belt and tensioner.... I went to fire up the eclipse... it spit and sputtered and won't run worth a shit.... I have a misfire, but can't figure out why. here are the specs. compression 135 across the board spark on all 4 - yes injectors (550's) 2.4 - 2.5 ohms B+ voltage at both side of the injector connectors 6.5K , 5.5K, 4.5K, 3.5K ohms on the 4 spark plug wires from longest to shortest respectively so I have spark, fuel, compression.... all that is left is timing right???? after the timing belt job I spun the motor over by hand 6 times and every rotation I checked the timing marks and they were right on. what is left???? -------------------- You CAN sleep in your car, but your CAN NOT race your house!!!

it misfires at all RPM's
the iridium plugs have come out a year ago or so and BPR7ES NGK's went back in.... I did pull them and they were severely carboned up, I cleaned them up with the mini sand blaster at work and re-installed them.... no change.... after speaking with NCgalant I will be doing a boost leak test (important due to draw through MAF... BTW.... MAF data shows extremely high..... 120 Hz at idle and over 200 Hz at 1800-2000 RPM -------------------- You CAN sleep in your car, but your CAN NOT race your house!!!
