Thanks for posting

have you had a chance to check for any diagnostic codes, do you happen to have a code reader or can you rent or borrow one? If there are any codes in the computer it would help a lot.

It may be a crank angle sensor or something else that's shutting the injectors off.

A little history may also be of some help, how did this come about? Was there any loss of power, misfire before this happened?

My wife said the car had been sputtering and running rough lately. I thought it was due to moisture from all the thunderstorms we've been having and puddles that she was driving through to get down the driveway. I don't have a code reader

I had a code reader but it took a crap on me

Thanks for the reply

A common problem on these engines are the ignition coils, one on each spark plug but I don't want to just guess at this and waste your time and money, anyway you can rent a reader and then get back to me with some code information?

Have you remove dhte spark plugs to have a look at them? there may be a clue there.

Customer: replied 3 months ago.
I have not. I replaced them about a year ago. The car isn't a daily driver. It has 2 coils that fore 2 plugs each.

I sprayed ether into the intake through the pvc hose. It didn't make a difference in the way it ran or the duration of run time
Expert:  Ted Ritter replied 3 months ago.

Not a fuel problem then, see what you can do about getting some code information and let me know.

Customer: replied 3 months ago.
Yeah. $135 and a new fuel pump later. Lol��

My motto is: always check for computer codes first,

Decent motto

I have an iPhone and I know it can be used as a code reader but I'm not sure where to get the app and plug ins
Expert:  Ted Ritter replied 3 months ago.

Y​ou probably need an interface of some sort to plug into the diagnostic port, it may be more convenient to just get another basic code reader, you'll most likely need it again sometime.

Yeah. Like trying to figure out why this Hemi ram with the off road package will pass everything but a gas station
Expert:  Ted Ritter replied 3 months ago.

I can imagine that. see what you can do.

I was referring to the Corolla.
