update on z32 maf on noncharged side
update: CAR NOW RUNS...
Figured out the problem..I bet you guys wouldnt guess what it was...............
A bad coil pack...And when i mean bad, little sparks were sparking on the top where the connector was...
Good thing i bought some used coils packs...replaced the bad one, and bam, no loopy idle or stalling during idle and while driving...went for a test drive and WOW...well..my intake pipe kept on blowing off...so..going to get it beaded and get some t-bolts and im set....
WOOHOO!!!
Sorry..so excited...
1992 Maxima VE30DE turbo
hks ssq bov
370cc injectors
z32 maf
jwt ecu
NOTES: 1) BOV does not reciruclate back into the intake.
2) Breather pipe vents to atmosphere.
well..today I installed my hoses and maf on the noncharged side of the turbo...
Started the car up and it started fine...idled fine for maybe a couple minutes...No more of the continuosly looping idle....................................
BUT......idle falls intermittent maybe once every minute...like the engine wants to cut off..car stalled once when i let it idle....
I let the car warm up, then i drove it like a grandma, and I get the bucking but its not as alot when the MAF was on the charged side....its weird because when I step on the gas, and then the engine bucks, im still stepping on the gas but its not going anywhere, then it would go...(for example...(pause(engine bucks), then it plays(engine is alive))...When the engine would buck, I just shifted into neutral, and the car died out..so I had to restart it while the car was rolling(this just happened once)...
Anyways...Dont know what to do....
Could it be my BOV not recirculating???
Could it be my breather hose is venting to the atmosphere????
I tested for any vaccum leaks, and their were none....

Its ok for the breather to vent to atmosphere but the BOV venting to the atmosphere is wrong...
Any Air that gets metered by the MAF HAS to make it to the engine...any air that leaks out, the engine will be confused, as is your set up

Ok..i understand that, but what about my idle problem...Air is not venting out of the BOV during idle because it it closed...And I still get that engine feels like it want to cut off at certain times...I dont have the continuos loopy idle anymore..but sometimes, the rpms will drop like the engine is going to die....

possible cause is IAC but it could be others 2
i would suggest rasing your idle to 1k and see if that helps
