My 03 es is starting to die when I'm at like a light or just parked with. It idles real rough then just drops off. Any ideas?

 

Any help appreciated. I'm at work as a delivery driver and it sucks right now. It happens also I go into a turn with out giving it gas.

 

pinch one of the purge solenoid valve hoses and see if it picks up.

Any trouble codes?

 

I'm sorry but I'm not sure what a purge solenoid is. Where is that? I'd assume on the intake side

 

yeah, it's near the EGR solenoid, right in the middle between the valve cover and the intake manifold, if you're standing in front of the car looking at the engine, the EGR solenoid is on the right, the purge solenoid is on the left, right beside the PCV valve which is the short hose that goes between the valve cover and the intake manifold...looks like this:





also check for any other vaccum leaks...clamps on the intake tube, MAF sensor housing, throttle body, and any rubber hoses connected to the intake manifold.

 

The problem just went away? So confused

 

Did you have a bad batch of gas?

 

I'm not sure, I have been using supreme recently and nothing else

 

unless your ECU is tuned for supreme, you're wasting your money.

 

Well now that I have a tactrix cable I can tune for supreme?

 

sorry, but your previous post struck me as "i use premium because it's better"...premium fuel could still become contaminated..."bad gas" doesn't mean low octane...

of course you can tune for whatever fuel you'd like to use...though depending on how aggressive you tune, you would have to strictly use that fuel brand/grade to keep consistent results, with minimal risk...

 

Oh ok. I still have a lot to learn with ecuflash and evoscan

 

it is an 03 es, are you modified at all?

 

Catback. And short ram intake

 

either your MAF or IAC is pooched or you have a vacuum or emission leak is my guess.
