- FOUND:We verified the concern and found that the engine is consuming too much fuel due to a lean mixture condition. Essentially, this means there is too much air and not enough fuel. Upon inducing smoke in the intake system, we found that the intake manifold has new cracks, causing vacuum leaks. Regarding the next concern, which is about the car driving poorly when starting from a stop, we were able to verify that the problem comes from the transmission. We found codes related to low pressure and problems with the correlation of gear number 1. This indicates that with a good oil level but low pressure, the pressure is escaping from somewhere. In this case, due to the high mileage, we can agree that the leak is coming from the clutches. Now, regarding the fuel level, we proceeded to check the entire circuit that integrates the cluster computer, the wiring connected to the level sensor located directly on the fuel pump. We found that the pump's level sensor is working properly and producing its corresponding signal. However, we found that the cluster is not testing the correct voltage, and this creates an anomaly in the fuel level reading. We found that the cluster has failed and needs to be replaced or rebuilt. For the turn signals, the integrated circuit that runs from the switch to the lights was checked. We found that there are no problems with the lights or the turn signal relays. When backtesting the switch connector on the steering wheel, we found that the signal has errors, caused by a false internal contact. The turn signal switch has failed. Regarding the antifreeze leak, the system was pressurized to the manufacturer's specifications, and we found that the leak originates from an outlet on the timing cover. We found damage to the corroded aluminum part, which was cleaned, and the clamp holding the hose was replaced. The system was then pressurized again, and for the moment, the leak is not recurring. If the leak will return, it is recommended to replace the timing cover.
