Question type: Maintenance & Repair

OK, FIrst off my biggest mistake was going through carhop. I bought an 01 galant. When I
bought it. Everything seemed fine. THen the service engine light came up. Came back that it
was the cat warmup effiency. So a friend of my mine checked my cat said it was bad. So he
threw a pipe on their. But the car still dies once it heats up. I have to drive with both feet!
Frustrating. ANyway it starts to idol low and then dies out. We changed the spark plugs,
replaced the cat, not sure what else it could be. ANyone have any suggestions???

Have you checked for warped or cracked head(in the early stage) or there may be a sensor going out when operating temp is reached. Just throwing some options out there.
