Update on Phinally

By Phynally

Filed under: 1990 Chevrolet Corvette (Phynally's Phinest)

Last summer everything with the engine performance came to a head. Gas mileage dropped to 12-14 mpg. It was to the point it barely run and sooted the tail pipes in just a few miles. To the shop it went. The computer was replaced. Got another custome programmed chip. Typical tune-up was done with plugs, wires, cap, rotor, oil change and then all the sensors were checked. Then came the biggy. I had the fuel pressure regulator and injectors replaced and that fixed the issues. Gas mileage jumped to 23 mpg the day after I picked it up. One thing though. I thought it was a bone stock engine, but after all the crappy running previously I was unable to detect that it has had a cam change. It has a rumpity, rump at idle. My mechanic and I can only agree on the idea that the cam is a mild street cam. It runs like it has much more hp than stock. I'm completely happy with it since the mpg is doing no less than the new car estimated mpg.

Since then I've had the U-joints in the rear axles replaced and it's in the shop presently having the head gaskets replaced since I blew one on them this past week. I've had to use it for a daily driver the last few months and I really need something else to drive to work. I want to park it back under the carport under the cover. I just really want a beater truck to use for work.

Anyway, that's an update in a nutshell.
