| LT1 EGR Question |
Subject: LT1 EGR Question by VtVette on 2010/5/3 2:59:02 Hello guru's a question about the EGR System on my '93. Since I bought my '93 the 2nd gear syncro was bad. This past week I finally swapped out the 6 speed with another unit. Unfortunately while removing the exhaust the studs on the manifolds snapped off so I had to remove the exhaust manifolds to extract the studs. While trying to remove the EGR pipe the pipe cracked so, as a temporary fix I cut the EGR pipes flush with their retaining nuts and welded the nuts solid. I then made a block off plate for the port in the back of the intake manifold (where the pipe that connects to the right side exhaust manifold connects to the back of the intake). So I got the car finished up tonight and took it down the street. It started and ran great, no check engine light at all. It now seems to have a backfire at higher RPM's, and sometimes when blipping the throttle sharply. The engine was pretty cold, I went no further than a mile at the most. I did not have a chance to look the car over tonight as I had to get going but I want a solid plan of attack for tomorrow. My first thought is that a plug wire is crossed/not installed all the way. If this is not the case could removing the EGR pipes cause this backfiring? I didn't think so as others remove their stock manifolds in place of headers etc. Any thoughts or ideas would be appreciated thank you. |
