Hi, been troubleshooting my stalling problem and thought I'd throw out what I have to see if anyone more experienced can chime in. Recently had a leaking IP changed at a shop, since then with the "new" used pump, the car will stutter and sometimes stall when driving, but never when idle. Once the engine gets up to temp, I start seeing air in the clear line to the IP. Was thinking it could be a restriction in the fuel line making too much pressure on a seal somewhere, or just a bad seal.
I pulled the sending unit, looked fine but I cleaned it out. Its the later model without the return valve anyway. Replaced some screw style clamps with the spring type and the t-valve on the fuel filter since those seem to be common leak spots people mention. No change.
Relay 109 is new.
Just got VCDS on it today, and got more than a couple codes:
17978 - Engine Start Blocked by Immobilizer
P1570 - 35-00 -
16612 - Throttle Pedal Position Sensor (G79)
P0228 - 35-10 - Signal too High - Intermittent
16705 - Engine Speed Sensor (G28)
P0321 - 35-10 - Implausible Signal - Intermittent
16502 - Engine Coolant Temp. Sensor (G62)
P0118 - 35-00 - Signal too High
That's a lot of sensors. I was going to start by checking the connector and ohms on the engine speed sensor, as I've seen a thread about it causing similar to what I'm experiencing. My door remotes don't work and haven't for awhile, the locks themselves are also quirky. I was told these are all controlled by the ECM- the same computer that manages the engine? Wondering if I should just be changing that computer out. A check of it's connections seems to be in order, at least.
Thanks in advance for any suggestions or correction!
