Auto TSI AWD with flooding

[AmirTech]

Hi guys,

Here is my car specs...
1997 Eagle Talon TSI AWD - 90K miles
UIC pipe - 1G BOV
K&N
boost set to 10PSI (around stock).
Boost guage plumbed into FPR line.
Removed fuel pressure solenoid from the path.

My side mount bolts broke, dropping my engine 4". I had to have the broken studs tapped, and replaced. I cut off the AC belt for now (doesn't hurt it). I drove the car home fine, everything started fine.

Next morning...it's around freezing (33F). Car starts, warm up for a minute. Go to Reverse, backup a little. Go to drive, RPM drops like crazy, and car stalls. The car won't start.

So I was in a hurry so I pushed the car back in it's spot. I grabbed the other car and went to drop off my wife at work. I came back home and started it again. Started fine..idle fine..everything good.

Now, I tried to run a test. I shifted from Park to Reverse, to Drive...back to R...back to D...back to R...sometimes the car RPM would drop but pick itself up..I could see the RPM going down to about 500.

Well at one point, just after a shift, it doesn't catch itself and it stalls. Then it won't start.

I crank away like a maniac and it won't start. I get out of the car and can smell fuel. I go under the hood and can't find the smell...

This feels like the car is flooding up.

I had a problem with the temperature sensor and that I replaced. The car has brand new Denso 3066 (BPR6ES equivalent from what I read) that the mechanic put in.

So the question is...

Something in the engine dropping caused something to happen...is there a sensor related to the tranny? Has anybody had these symptoms?

I appreciate any help .

thanks,
Amir

One more thing...

The boost guage was reading 0 while I was cranking and not able to start.

So tonight..I came back home..I started it up...let her warm up. I was looking around the engine bay for something that was disconnected while waiting. I tried my typical R, D, R deal...I did get RPM to drop somewhat..but it didn't stall.

What really sux is that when it does STALL (and that is easy to get it to do) for some reason it won't start again...that's what really confuses me. I can live with an occasional stall...but I want to be able to start it again.

What do you guys think can cause that??

I feel like it's stalling becuase the ECU is dumping more fuel than needed during a shift (ie. going from Reverse to Drive).

Is there something that tells the ECU that I have changed from Reverse to Drive??

thanks,
Amir

Clean injectors and check for flow. You might have one leaking during a long stop and is flodding a cylinder.

Thanks for the replies.

I'm going to do 2 things...

1) Buy some Seafoam and clean the intake fuel injectors, etc.

2) Buy some 550CC (might as well upgrade) and replace the injectors.

I might also pick up a replacement FPR if that proves to be a problem..but usually bad FPR reduce the fuel pressure and not increase.

Hi guys...

I bought 2 cans of SeaFoam..and a replacement set of plugs.

I put 1 bottle in the tank..the other I used to suck in via the hose that goes to the BOV. 30 minutes down time...then drive the crap out of it for 5 minutes.

I just came back from that ride. In a couple of hours, I'll switch out the plugs and then let's see how it does tomorrow.

I'll keep everybody posted. Might help some future dude with the same probelm .

thanks,
Amir
