if i make boost, say 5lbs, and let off the gas.... the engine dies.

any ideas?

piggyback PMS

72mm turbo

306
 
Where did you put your BOV? before or after the mass air? What kind is it? You might need to clock it.
 
how have you setup the boost tables in the PMS? I had an issue similar to this last year and went through the entire boost tables to redo everything. I dont know what numbers I had wrong but after going through it everything was good again.

i havent touched them..... what did you do? just add fuel under boost?
 
yeah, mine went lean right after getting out of the throttle so I added a little bit, I think I added it in the idle/ light load table too. are you using the idle control with the PMS? if so try tuning without it, it caused all sorts of issues with mine so i just tuned without it.
 
negative ghost rider........

new problems arise too!

when i first tried starting the car, #5 cylinder filled with fuel. i started pulling plugs, when i got to #5 fuel squirted out, which tells me it was under pressure.......not good. i thought the injector was bad, livernois checked it out, comes back good.

i get the car running through PMS problems. runs and drives fine ( unless under boost )

i change plugs and #5 is all wet, looks like new, where the rest are rich/black.

so on advise, i switch #5 injector to #6 hole.

go for a 30min cruise tonight.........pull #5 and #6.............#5 is all wet, #6 looks fine......

any ideas?
 
no spark in #5??? bad injector, wire,cap/rotor etc?

you should be careful about the fuel loading up in your oil... change it soon
 
Has the injector harness been messed with in anyway? Are the wires reversed?
Are you sure the #5 spark plug is firing?
When the car is running pull the #5 wire and see if the engine stumbles or no change.

It should have the most draw on the ignition system at idle. You should be able to tell if it's running rough on 7 cylinders.
 
put a diode light on the #5 cylinder and see if its pulsin gthe injector... It might just have the ground side rub thru to ground somehwere and its on full tilt all the time.

cap and rotor are new, and there is a mark on the inside of the cap on the #5 post ( like the rest of them ) i know "new" is not always good either

Duke went through the harness but i am sure he didnt mess with that. i will look for the wires this morning, but again i am sure he didnt remove the connectors. are you trying to set me up? if i reach down there and pull that wire.....i am now ground.......and that hurts, ask me how i know!
