I have a stock D15Y7 that throws an 02 code... 02 has been replaced several times and it always comes back. Unfortunatly this is not my main problem. Recently I warmed my car up for about 10 mins outside of work, once I got in and pulled out it began missing very badly and shut off... not to be started again. I towed it to a garage where they changed the plugs, cap, rotor, fuel filter, and adjusted the timing. So I drove it tonight and it misses badly under moderate to heavy acceleration.... its fine under a light foot. Also when stopped at a light the RPM's drop very low and it misses slightly. I just replaced the entire distributor about 2 months ago. The only thing else I can think of is injectors or ECU. Anybody have any suggestions/similar problem?

 

ugh...I hate these kind of problems.

First thing to remember is to do the cheapest repair you can first and then work your way up.

Some injector cleaner in the tank might help. Im kinda guessing you should check the fuel pressure, possibly a fuel pump going out. Change out your fuel filter also.

What color were your plugs when you pulled them? This is really important to know.

Hows the cat? Place your hand over the exhuast while its idling...there should be some pretty good pressure there...if it feels plugged that might be why your throwing that code.

I got stuff all scrambled in there (worked all day and then came home and worked on some remodeling on the house till midnight...brain is pretty spent ) but there should be a few things to help you out.

 

The fuel filter is brand new, and my cat is hollowed out. The plugs were fine when they were pulled, and were changed as a precautionary measure. This really sucks.

 

i think its time for a swap.
