Hello! A quick suggestion, could your Catalytic converter be blocked/collapsed. This would restrict the full flow of exhaust gasses from the engine thus causing severe lack of power.
Happy New Year!

HOW DO YOU KNOW IF YOU HAVE A BAD TORQUE CONVERTER


The two most common failures in torque converters are excessive slipping due to bad seals and locking problems. If the torque converter is slipping, you will have poor acceleration, but the engine will rev up quickly. It is especially noticeable on hill climbs; engine RPM will be high, but the vehicle does not go as fast as it should, and in severe cases may not be able to climb the hill.

Lockup problems may be harder to detect. At highway speeds, most modern torque converters have a locking mechanism to eliminate slip. Failure to lock may not be noticeable except as a decline in highway fuel mileage. Failure to unlock is readily apparent; the engine may stall on deceleration, or hard braking is required to slow the vehicle, which then stalls.

Remove the front o2 sensor from the exhaust system and if performance improves that means you probably have a plugged catalytic converter which will need to be replaced

My jeep will not accelerate when it is in gear. it does start and run good while its in park. it will sputter and seems to back fire


cat converter is going bad. have someone rev engine and feel for pressure at tailpipe. i am willing to bet its restricted. did you have the egr fail code? egr valves hardly ever go bad. a bad cat converter will not allow for normal aceleration, even with the pedal to the floor.

Car drops out at 2700 rpm and sputters


There is a rev limiter in these cars that disallows over revving in park or neutral. Does it climb past 2700 under hard acceleration?

Acceleration


I belive this to be a tps. On a xg300 it would rev up but not accelerate. try turning the car off and restart in. best of luck.

Also try ebay. You want a DIRECT ECU wiring chip not a intake resistor. Should increase Horsepower and torque around 20%.
