... So...

DEpointfive0 · 05-05-2013, 03:59 AM

Driving on the freeway (lets say I'm a billionaire and I closed it down for a night) going 90, music on loud, AC on full blast, then I feel this popping/shimmy from the motor, what I assume to be multiple misfires, and the car's CEL rapidly blinked at me and it car decelerated to 75... Then as I was pulling over... Car ran fine, no CEL, fùck it, kept driving.
Came home, OBD scanner doesn't read anything. Are they saved somewhere where the dealer's scanner can read it?
Any ideas?

Oh, and this was also a previous problem:
Problems Starting ;-(

Some DTCs are "permanent" (until you manually clear them) and others will clear themselves when the error condition disappears or a drive cycle has been successfully completed. Make sure that your scanner is looking for all DTCs. If nothing shows up, you might want to leave the scanner connected for a while so you can read the error code if it happens again.

I'm guessing that you had an injector problem (piece of dirt?) that eventually cleared itself, but that's just a wild guess at this point.

Edit: Read through the topic you linked to. Have you checked the crank position sensor? It could cause your symptoms.

Well, nothing has been checked really... Dealershit said battery, then I opened a case with corporate...
I'll be taking my car in again soon...

Did you just fill up the tank before this? Did you run the tank low at some point before this?

a part of me still thinks it might be the fuel pump.

good luck!

I ran REALLY low 4 days before, I was at about half a tank when it happened

God knows at this point... I'm praying for a crate motor swap or a buy back...

Running low on gas?? What does that have to do with this at all? If FI and running high boost then yea I could see that. But he's NA. Countless people sometimes run low on gas. That has nothing to do with the problem here at all.

Good luck DE, worst case hope for a motor swap!

Running low on fuel can cause the fuel pump to suck up an sediment in the tank either choking off the pump or causing an injector to clog. Thus causing the car to think its fuel starved and protecting itself.

also the fuel in the tank helps to cool the fuel pump. running low constantly can harm the pump.... i guess :/
