**THIS IS JUST FOR AN IDEA...IM NOT RESPONSIBLE FOR ANY MECHANICAL OR PERSONAL DAMAGE get ready for a fight lol i found it easier to remove nose panel to gain all the access you need with stock intercooler and afm setup my AIT was at 120 cruising down the highway...today driving to work...

i used taylor 10.5mm(or maybe they was 10mm) on my 01 silverado with a 4.8 v8 had no problem and the guy i sold the car to 5 years ago still has them on the the motor and only change plugs once

update... did a little work to the old girl install godspeed fmic, rerouted IC piping a little, removed afm, replaced accordian hose with 3in piping, cone filter, install 2.5 in straight pipe exhaust from cat back, repaired a small coolant leak at upper radiator hose, replaced burnt out...

remove the easiest plug wire to get to...insert a spare or old spark plug lay spark plug on the valve cover or the highest point crank engine and look at spark plug...night time makes it easier.... swap the efi fuse out anyway with another 15amp fuse...then see if it runs

let me go round up the unicorn ;)

have you tested for voltage at ecu terminals? have you checked the efi fuse? did you use a multimeter to confirm 12v on both sides of fuse? no CEL no ecu

why not check for no spark rather then guess???

start from step 1 confirm you have fuel, spark and air

hows it idle? smooth? did you test the new afm per tsrm? also i just remember the E1 ground wire running to the afm on my 87 had a break in it causing my car to run good sometimes and like shit other times ran a ground wire to the passenger fender well...presto no more issues

i thought you as well was lex/550's but with a safc???

holy mother of all supra take offs both sound very nice im impressed with the supras ability to launch and pull on the mustang good race

my vf at that afr would go 0.00volts...means the afr is rich and the ecu is now pulling fuel to correct this everycar is different...some cars vf will go to 2.2 or 2.5 volts where its happy...others like mine are at 2.00V i see you have the lexus/550's...did you tune it first to obtain a...

my idle at cold start is 14.7ish my idle after cold start is 15.2 this is where my VF signal from ECU is happy at a 2.0 volts which at that voltage the ecu isnt working as hard to obtain its desired voltage im using maft pro in speed density

small info update today cruising to work at 70 mph 2,500rpms my AIT was 117ish in 98 degree weather parked it and let idle...AIT was showing 180 degrees so later tonight i will be moving AIT down by passenger fender...will update new temps tomorrow since it will be the same temp tomorrow

same as npr's problems with ringlands breaking a few forums i searched around always had 2 or more broken pistons due to ringslands that came from the same motor Get what you pay for!!!

what are you using as far as a tuner? piggyback or standalone? 13-14 at idle is to rich... mods? check turbo shaft play?

After installing my maft pro in speed density I have been having some problems getting fuel cut to raise After a few weeks of playing around with settings and ve table I'm stumped 1 think I was thinking could be my location of AIT sensor. I have it mounted in the 3000 pipe After driving...

i just googled npr pistons breaking and came up with they have issue with ringlands cracking...most guys where in the 400whp range http://www.supramania.com/forums/showthread.php?132035-npr-pistons
