Hey all, I have had a very long rough day with my 240 wagon and need a little advice. It's been a long day so please stick with me here.
Since I'm a student I do my own car repairs in general when I can, so I decided that since the injectors are original that I might as well replace them. The ones I ordered were rebuilt bosch from ebay, and have the "4 hole" sprayer while the old have a needle. The car was running rich and injectors are probably the only thing that hasn't been replaced.
All went well with the injectors, and I moved the car a few parking spots down to park outside my apartment window (for electricity if needed). I then replaced the in tank fuel pump. When the last pump died, I installed an aftermarket, and it seemed to have died. With a multimeter it showed some draw from the pump but no life, so I swapped it for another one today. The new pump was too long and needed modification, and I cut and spliced wires together for the new harness (I guess I should test for continuity tomorrow on these). After this the car just would not run right. I started it up and it idles alright, but seems to keep dropping about 100-200 RPMs in a pattern. When I give it any gas the engine starts violently shaking, tries to stall/sometimes does stall.
So I installed the old pump back in, and was able to move the car to a more safe spot to work on it/keep it sitting. It runs better but when getting a little gas it "catches" like it is about to stall, but quickly recovers. The car is too loud to work on during the night hours so I had to hang it up. The show gathered a crowd of residents who know a little about cars, and a few thought the new pump may be clogging.
Here's a small list off the top of my head of all that has been replaced by me. Some may or may not be important.
Timing belt
Coolant temp sensor
Crank position sensor
New wires, plugs, cap, and rotar
Fuel pressure regulator
Throttle position sensor (adjusted only)
Intake manifold and exhaust gaskets
Main fuel pump (bosch) and filter
Fuel pump relay
There may be more but nothing very important. This wagon has 56k miles on the clock with all service records, but at this point everything is old going. For a very long time it has run rich with a bit of a gas smell from the exhaust which is why I have replaced so many odds and ends.
