Ignition Problems

The Camaro has been doing 90 miles a day taking me to work and back without too much hassle, apart from when we had a week or so of freak weather and it was raining so heavily it was a struggle to drive at 30mph on the motorway. The car got so wet that the optispark distributor got soaked and was misfiring and popping through the exhaust. It cleared up once it dried out a bit but it’s had an occasional miss ever since.

I moved the air intake up higher as it was wet when I checked it, and did a week of logging and tuning which smoothed it right out but I still have the miss. I’m 99% sure its the distributor, but as it’s a pain in the ass to change and quite expensive I decided to fit the MSD box that I had waiting for it and see if it sorted it. It has cleared it up quite a bit, but it’s still there so I guess I’ll have to just get on with it. It’s also had really bad steering and was eating front tires. After a lot of checking I found the idler arm was worn and it was moving to an inch of toe out from being slightly toe’d in when set up. With that done, it’s a lot better but I’m swapping the rubber bushings for poly ones and getting it set up again.

New Engine

I’d bought a complete Camaro LT1 and 4L60-E off ebay a few years ago and planned to freshen it and replace the Impala one. I got Zane to strip and check it and he found no problems so I ordered up a full set of gaskets and a beefier cam and he rebuilt it ready to swap in. While he had the car I got him to make a new exhaust system for it in stainless and subframe connectors to stiffen the car up. The new exhaust gave me loads more clearance so I can now get over at least some speed bumps.

Subframe Connectors

The engine runs well but one of the lifters is sticking so it’ll need the intake off it and fresh ones stuck in. It also doesn’t like to idle so low with the new cam so I had to bump the idle up slightly, and wire a park-neutral-park switch in to stop the car stalling as it goes into gear. The ’95 box also needs an extra wire to control the torque converter lockup so it’s running unlocked all the time for now. It’s nice just driving it again instead of the Volvo I got as a spare while the work was getting done.
