So I'm hitting a bit of an interruption in accleration around 3300 rpms in my 86 N/A, not a flat out cut or hesitation, it just slows down a bit. The AFR's lean out during this slow period, and I've made the decision to re-do the grounds for the ECU of course.

However there are 4 or 5 different grounds at the ECU, should I reground ALL of them? Just splice in w/ 14 guage, join the splices with a 10 or 12 guage, then run that to the block?

Newb question, sorry....

Thanks,

i'd just clean the existing ones, as that is probably the actual problem.

 

www.aaroncake.net has an excellent guide for this. I strongly recommend it.

Read through the guide once first to see what parts you need, then go get them. There's only 1-2 grounds I'd actually redo: the ECU and the ground it says to add. For the rest you clean the connections, replace the bolts, etc.
