My 2000 Astro bogs when you accelerate. Fuel pressure is good (58 lbs.) Fuel filter has been changed. The strange thing about this problem is that the car runs fine when the mass airflow sensor is disconnected. Although it does shift very hard between first and second when you drive it with the mass airflow sensor disconnected. I changed the sensor and the problem remains the same. Runs with it disconnected bogs when connected. When I say bogs I mean severely bogs. The car will barely reach 35 miles per hour. Help!! Couple more things. Only 33000 miles on car. Fuel pump also has been changed. Temperature sensor has been checked and is working. Also problem gets much worse when engine warms up.

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Use the reported dealer finding as the starting point if reviewing the repair record. If symptoms recur, have exhaust restriction and the original drivability complaint tested rather than driving with the airflow sensor disconnected.

For those who may have this same problem-I finally caved in and brought the car into the dealer. Problem-Clogged pipe in the catalytic converter. The good news is that the converter was under warranty for 80,000 miles. No charge. I never would have guessed it with only 33,000 miles.

Discussion summary

2000 ASTRO

A 2000 Astro severely bogged with its mass-airflow sensor connected. Disconnecting it improved running but caused harsh shifting. Replacing the sensor and other fuel-system parts did not resolve the complaint.

Reported outcome: The owner reported that the dealer found a clogged pipe in the catalytic-converter assembly and handled the converter under warranty.

The final update identified the dealer's finding but supplied no measured restriction or long-term follow-up. The historical warranty experience does not establish current coverage.
