I have 91 civic with a b16a swap... my problem is when i let it go sometimes it bogs.. the rpm will drop down and few seconds later the will shoot back up and go. Anyone know what the problem might be?
thx for ur help.

 

clogged injectors?

 

Thx, i will get cleaner for it.

 

change your sparkplugs. i changed mine and made a world of difference. I had the worst bog you could imagine with the wierdest noises coming out of the exhaust and sounded like a freaking subarau. i changed them and it goes so smoothly now.

 

It's Subaru lol, and change your fuel filter.

 

i did the plugs and wires, and now im going to try the filter.
