The car is an 89 HF with a 91 Si swap. A little over a year ago I got a new dizzy from distributor king. I havn't driven the car much and it has maybe 900-1200 miles on it with the new distributor. Now every so often it'll throw a 4 and a 9 codes, which I was told was the crankshaft position sensor and cylinder position sensor. It bogs and sputters with low load and little throttle, runs very nicely from 2000-3000rpm, then hits rev limit at around 3500. I was told this was honda's idea of a limp mode. I do not have any receipts or proof of purchase from distributor king and it was probably around 14-15 months ago when I bought it. My friend borrowed the coil out of it at one point and lost one of the terminal screws on it so I stole a small screw from my angle grinder and it works fine, but it's ovbiosly not the right screw. Will they still cover it under warranty even through it's been mildly tampered with?
