Random stalling of the engine??

XtreeX · 11-12-2006, 05:24 AM

**checking codes as of right now**

Okay, well I drive a turbo 5-speed 87' and I recently (like a week ago) had the head gasket, water pump, spark plugs, sparkplug wires and timing belt changed; and the lady who sold me the car had records of the clutch being replaced about 30,000 miles ago. The only mod I have done is the bosch 110 bov. Otherwise it's bone stock.

Basically i was taking a curve (not a turn) and my car just up and died. Power was on but engine just died. Now before this happened my car was boosting to about 5-6 psi and would accelerate in 2nd and after about 3-4k RPMs the acceleration would level off. It's hard to explain but in 2nd gear its a constant acceleration and force until about 5k rpms but it would level off around 4k'ish rpms. I cant afford anything else!!

What could this problem be? The check engine light flickers on and off, and I have NOT done a diagnostic yet (since the light doesnt stay on). Please help! If you need anymore information to help me diagnose the problem please let me know I am in dire need!!

Yep, just did a diagnostic and everything came up normal it just blinked repeatedly... i'm so scared LOL!

seems like your car is chocking
maybe blocked cat?
maybe even broken?
when was the last time u had a tune up

Broken catalytic converter could cause my car to die in the middle of driving?

In terms of tune up, i just had the head gasket and a whole bunch of other junk replaced and oil change and all that.

Could it be bad spark plug wires and some of the pistons are misfiring? Also, I get it up to 5psi so my turbo is okay right?

When you jump the terminals to recieve codes ,the check engine light will flash every 0.25 seconds to indicate all systems normal.You had a pretty decent part of the engine apart and it's not impossible it was put back together slightly off.Does the car idle and respond as it did before the work?I would be inclined to suspect the timing or fuel delivery ,but I've been wrong before.Let us know any more symptoms that pop up ,and good luck.

thats the word i was looking for "timing"
that could be it, or combination of all of the mentioned above

my friends car is jus like that, after he drives it hard for about 5-10 mins
it dies in the middle of the road, but that was his turbo's fault it was jus too small for that car
i doubt that the problems with urs

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...

Supra2NR · 11-12-2006, 08:02 PM

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

XtreeX · 11-13-2006, 06:36 AM

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