Lack Of Power, Sluggish Or Spongy

If engine delivers less power than expected, or if there is little or no increase in speed when accelerator pedal is depressed, check the following items:

• A/C clutch disengages at full throttle (Metro and Tracker).
• Check throttle cable adjustment.
• Verify air intake or exhaust system is not restricted.
• Check fuel pressure.
• Check in-line fuel filter and replace if dirty or clogged.
• Ensure sufficient secondary spark exists.
• Ensure ignition timing and controls are working properly.
• Check ECM ground connections.
• Check EGR valve and solenoid operation.
• Check charging system output. Repair charging system if voltage is not between 9 and 16 volts.
• Check Torque Converter Clutch (TCC) operation.
• Check for faulty spark plugs.
• Check for defective spark plug wires.
• Ensure valve timing and engine compression are okay.
• Check for worn camshaft.
