After squeezing in a bit of time here and there in between customer cars, I managed to do some more diagnosis of the issue with the Cavalier. Read more
Spent the evening after getting off of work, working on the Cavalier. I swapped out the fuel injectors for known good pieces, and cleaned the upper plenum and throttle body. I also replaced the MAP sensor with a known good piece. The miss is still present. I believe the miss is being made more apparent by the worn upper motor mount on the passengers side, however, it still bothers me that I have not been able to track down the source. I am getting no DTC’s and all live Data appears within parameters. Out of frustration I pulled the valve cover, and checked valve lash hot. All was within specification. However, while running the engine with the valve cover removed. It became apparent that the sound was not coming from the rockers. To my ear, it is either one of two things. Read more
Got quite a bit done in the shop yesterday. I installed a new fuel tank, fuel pump, fuel filter and fuel tank straps into the Cavalier. She fired right up. Then I turned my attention to the crappy head unit they had installed, using the term installed loosely. It was in the dash, but not hooked up. The reason it wasn’t hooked up was because instead of using the correct factory plug-n-play adapter, they chopped off the harness. Frustrating! After patching the wires properly and installing the new head unit (just a Kenwood KDC-248U), I HAVE MUSIC! Now I need to upgrade the 4×6’s in the doors and the 6×9’s in the rear deck. Read more
With gas prices going up daily, my 98′ Silverado with a 350/5 speed is killing me at the pump. So I picked up this 97′ Chevy Cavalier. Read more
Arrived at the shop to find a pool of gas under the rear of the truck. Seems the Edelbrock Quiet-flow pump was leaking at the spring plug (replaced the rubber O-ring with a Viton O-ring), and at the inlet fitting. Would explain why the fuel cell was empty when I rolled it out yesterday. After filling the cell with a few gallons of gas, and letting it sit for several hours over a piece of paper, no signs of leakage were found.
