I have a 85 tpi 305 camaro rebuilt it 1,000 miles ago. The problem is the sparkplugs they still look brand new. They are not brown black or grey I mean they look like I just put them in. The only problem I have is a slight jerk or stumble at about 1500rpm's otherwise it runs great start's great hot or cold. I can't tell whether it runs rich or lean cause the plugs don't look like anything in my books they only look new. They all are firing pulled each injector harness off one at a time and you could tell a difference also pulled each wire off and they are all firing. The motor is compleltly stock except for a small cam. Why do they look like this. Need serious Help

I can't help you on the stumble but if there are no signs of detonation that is how a comp. controlled FI. plug should look.

Thanks for the quick reply I just thought it was weird that it didn't look like anything in my books
