Built a stroker in my 97 about a year ago. It ran fine for the first 4-5k miles. Before the stroker I had an issue where I could drive it normally, turn it off, and it would stumble after I shifted to second. The stumble would go away as soon as I let off the gas(shifting into thrid for example). I never looked into fixing it. Now the stroker does the same thing, only much worse and all the time. It doesnt matter if its cold or warm. As soon as I get through that RPM range it takes off like normal and will run fine until I have to accelerate through the range again. If I try to hold an rpm at idle it will fluctuate about 100 rpms and slowly fall. I disconnected the battery and held the key for 30 seconds, and it seemed to go away for the first 2 minutes then was back again. The o2 sensor has never been changed so I have one of those ready to go. I suspected maybe the fuel filter, but the auto part stores dont have it. Can you change only the fuel filter, or do you have to do the whole pump? Any other ideas?
