I recently just bought a 1991 GVR4. It ran just fine picked up great. The car is stock. I had took it to work which is 160 miles away two different occasions. And last week I was headed there and got 30 miles outside of town and the thing just all of the sudden lost power and started chugging. I can ease on to the throttle and it will go but as soon as you give it gas it dies. It starts just fine. Idles okay after warmed up but you cant drive it around. Someone told me boost leak. And another told me to gut my catalytic converter. Im jsut lost one what to do. I had to leave the car at home and my mom drove it for me and she said the check engine light started coming on and she said its getting worst. PLease help!!!
