Random stalling of the engine??

XtreeX · 11-12-2006, 04:47 PM

Well, I was actually wondering if a bad turbo could be the cause? I've never owned a turbo before so I wouldn't really know for sure, on the contrary it does boost up to 5-6 psi still... so maybe it's not that?

I'll be taking it back to the mechanics tommorow (monday) and have him look at the timing and the fuel. For the most part the dying of the engine is somewhat graceful lol, in other words it doesnt stall hard it just turns off... If the lights on the gauge didn't come on and the power steering shut off no one would ever know that it actually stopped running (stock exhaust -_-)

Anything else I should let him know to look at aside from fuel and timing? Thanks guys!

----edit---- Could it be the O2 sensors?? and in response to the post above the car DOES idle normally

This morning i was looking at my engine bay and noticed that the hose from the BOV was actually off a little bit... its the hose taht connects the Bosch BOV to the 3000 pipe. The side that was off was teh side connecting TO the BOV. if that makes sense... Could this actually be the culprit? Regardless, I'm getting smaller clamps to make it a tighter fit. I don't know how i missed it last night...

cuz maybe it was dark last night?

that maybe it you had a leak
the air that was supposed to be let-off by the bov was still in the system causing the car to choke and stall

well it was still stalling... how can i tell if the BOV is working properly?

Supra2NR · 11-13-2006, 06:03 PM

i dunt know about that

you can borrow a bov from another supra see if still stalls
im jus gonna get my car this saturday and more learning for me

or u know what
what about this
how far is rockford from chicago?
cuz most likely i will be cruising all sunday cuz im gonna get my car saturday
u can borrow the bov on my car, see if the stalling still happens or what not
unless there's chances that bov can get messed up too

Rockford is north of chicago and can take 90 all the way down/up and its about an hr and fifteen... Depending on traffic.

I appreciate the offer, its really generous, but I dont think that will be nessecary. I bought new clamps and hoses for the Bosch bov and made them extremely tight. So far, in the short 3 minute commutes i make to school and back, it has been ok. We'll see how long this lasts. I'm also going to replace my O2 sensors. I know with my old supra (90' auto non-turbo) it would die in idle until I got my O2 sensors changed, that seemed to help alot.

I'm gunna drive it for another week and see what happens. It would deffinetly be nice to meet up with another supra owner though, maybe once the weather gets nicer we could meet up in the Chi or somethin.

Guys one thing real quick... I noticed that my car doesnt make it to 60 mph in 2nd gear. I thought that if I was accelerating hard a stock supra could make it to 60 mph before redlining it... If this is the case could it be a bad spark plug/wire? The plugs I got for the car were like $50 from O'Rileys since I didn't have time to wait for toyota wires (it IS my daily driver after all). So could it be miss firing? Like only 5 pistons working?

Any ideas? I keep posting because I feel like you guys know more than the mechanics around town here. TIA
