It seemed almost an impossibility, but we finally got Caitlyn's car back together with much agony and suffering. We tested it out by driving down to San Diego to begin breaking in her new gears. We met up with Christian's dad and had an Easter luncheon to celebrate many things including Caitlyn's birthday since she will be back at school when it comes around.
The car ran very well. In fact, after Emily and Christian cleaned the throttle body and gave it a top engine clean, the misfires that plagued the vehicle went away. We had hoped that her engine stalling problem would go away as well, but more on that later.
When we came home, we had our own little birthday celebration with her with cake and presents.
We didn't do much else since Christian was absolutely exhausted from too many nights burning the midnight oil trying to get her car back together in time for them to leave for school. At one point, we thought that they would have to take my car back to school as we were afraid that we would not be able to get it up and running in time.
On Monday, I took the girls out shopping for supplies at the asian markets and so that they could visit with my mom one last time before they left. We still had to put many more miles on the new gears so that we could change the differential fluid before they left. All went well until we headed home and ran into a bunch of traffic. We got off the freeway to take the streets but ended up running into a lot of traffic and stop lights that didn't seem to work anyway. After sitting for several cycle of lights with our hot engine because the lights would not change for us, the car started stalling again. Once the car cooled down a bit, we can get it started but every time we had to idle for a length of time, it would stall again. It took a good 10 minutes or so for it to cool down so meanwhile, we were stuck in the middle of a road blocking traffic. We stalled a couple more times before we made it home.
Christian was home from work before we finally made it back. So once again, he had to burn the midnight oil trying to diagnose the problems with the XJ. We have tried many things thus far in trying to figure out her hot engine temperature problems. On top of cleaning carbon deposits in the throttle body and top part of the engine, he had spent a couple of evenings wrapping her fuel lines to prevent heat soak that we thought was causing the stalling issues.
After staying up late researching and using his pico scope to test her sensors, he found that the crankshaft position sensor would stop working when it got hot. It worked fine normally until it got hot. Luckily, he was able to find and quickly order a new sensor and had to pay extra for them to ship it out overnight.
On Tuesday, the girls spent some time packing and then regardless of the condition of the vehicle, we needed to attempt to put some more miles on it to finish breaking in the gears. All went well at first but eventually, we ran into more traffic and it began, once again to stall when we got behind the long lines of traffic. We eventually made it back home, but we were pretty frazzled and was not able to get as many miles on the vehicle as we had hoped. Most of the traffic went around us and did not have too much of a problem but Emily noticed that the only cars that had a problem and got mad at us were all the shiny new cars who just sat there in back of us even though our hazard light was on and wasn't moving.
On Wednesday, the girls finished packing. The new sensor arrived and when Christian got home from work, had to work again until nearly midnight, taking off and installing her new sensor and then testing to make sure that the problem was fixed. It was very stressful and exhausting. But basically, hours before the girls had to leave, the car was finally fixed.
