I have a 1995 Corolla and about a week ago the car died going through a signal. Pulled over got it started and it died again about a 1/8 mile down the road. Towed it to the mechanic and he said the coil cracked. So we replaced it and ended it up replacing the whole distributor and ignitor. The problem now is and he cant figure it out. But anyway the car will hesitate and stumble like the injectors are not getting fuel. Idles fine but when you get over 2000 rpms it will do it. I pulled a plug and it doesn't look that bad a little white/brown in color. What should I check out first. The car ran perfect before the coil went out.

I appreciate any advice you can give me.

Thanks
Bryon
