95 LT1, Strange problem |
Subject: 95 LT1, Strange problem by Eagle223 on 2007/4/1 17:59:00 Hello all, Just got my 95 Zf6 out from hibernation. Any how I recalled a problem I had last year coming back from Carlisle and a few other times. It seems if I run hard, for an extended period of time she developes a sort of high (4800+) miss that almost shuts the engine down. Only after an extended period of hard running. My only mods are a Hypertech PTM, LT4 knock module and an open air cleaner with a K&N. Any thoughts? At first I thought Opti, But now I'm thinking maybe a weak fuel pump. I don't want to just start changing parts. If the Opti was bad wouldn't it do this all the time? Any help is appreciatted. Thanks in advance. |
