Sounds like fuel starvation. 1) change fuel filter. 2) change fuel pump. GM pumps don't hold up to water in the tank (methanol fuel) very well. Its a 2003 so its probably time. Never replace as many parts as you have, without first performing an OBDII scan of the stored fault history, to avoid buying parts you don't need

1432

I think it is 1432

I would need to drive the car to even guess what might be causing this. Can you drop over to my home in western USA?

Some fuses are only hot when the ignition is turned to run and some are always hot and other are hot only when the fused part is turned on. so that is not your problem

Auto transmission not changing down to 1st stage while in motion ? You mean not down shifting to first gear ! Which transmission does your cavalier have ? Automatic Transaxle - 3T40 Automatic Transaxle - 4T40-E Some of this may be over your head , if so I suggest you take it to a qualified repair shop . Electrical/Garage Shift Tests Perform this test before a hoist or road test in order to make sure that electronic control inputs are connected and operating. If you do not check the inputs before operating the transmission, you could misdiagnose a simple electrical condition as a major transmission condition. Use the scan tool on the Hydra-Matic 4T40-E transmission for valuable information and accurate diagnosis.

1. Move the gear selector to Park (P) and set the parking brake.
2. Connect a scan tool to the DLC terminal.
3. Start the engine.
4. Connect power to the scan tool.
5. Verify that the following signals are present on the scan tool:
?€¢ Engine speed (RPM)

?€¢ Transmission input speed (Turbine)

?€¢ Transmission output speed

?€¢ Vehicle speed (miles/hour)

?€¢ A/B/C Range

?€¢ PRNDL select

?€¢ Desired PCS

?€¢ Actual PCS

?€¢ PCS duty cycle

?€¢ Brake switch

?€¢ Engine coolant temperature (Coolant)

?€¢ Transmission fluid temperature (Trans Temp)

?€¢ Throttle angle (TPS)

?€¢ System volts

6. Monitor the BRAKE SWITCH signal while tapping the brake pedal with your foot. The brake switch signal should be:
Released -- when the brake pedal is released Applied -- when the brake pedal is depressed
7. Monitor the PRNDL SELECT signal and move the gear selector through all the ranges.
Verify that the PRNDL SELECT value matches the gear range indicated on the instrument panel or console. The gear selections should be immediate and not harsh.
8. Move the gear selector to Neutral and monitor the throttle angle signal while increasing and decreasing engine RPM with the accelerator pedal.

The throttle angle should increase with engine RPM. Functional Test

Missing Tech 1 Data Value Examples Table 1: Engine 1 Table 2: Engine 2 If you have completed the On-Board Diagnostic (OBD) system check, if the diagnostics are functioning properly and if no DTCs display, you may use the Typical Scan Values in the table below for comparison within the appropriate transmission. These typical values are an average of display values recorded from normally operating vehicles. They represent the display from a normally functioning system. You should never use a scan tool that displays faulty data. The problem should be reported to the manufacturer. The use of a faulty scan tool can result in misdiagnosis and the unnecessary replacement of parts. Only the parameters listed below are used in this manual for diagnosing. If a scan tool displays other parameters, the values are not recommended by General Motors for use in diagnosis. Scan tests are performed under the following driving conditions: ?€¢ Idle

?€¢ Upper radiator hose is hot

?€¢ Closed throttle

?€¢ Park or Neutral

?€¢ Closed Loop

?€¢ Accelerator OFF

?€¢ Brake not applied

Parameters that are marked with an (*) asterist are also valid in the Engine 2 list.

going from a 205 to a 195 is going to be a narrower tire. I am doing this now on my truck. I am going from a 305 to a 275. going from a 70 to a 65 is going to be slightly shorter of a tire. the opening will still be 15 inches. hope this helps.
