1999 Subaru Forester Repair Question
Poor Engine performance after clearing check engine light (follow up to previous question)
Original Question ( had $10 donation):
Vehicle - 1999 Subaru Forester AWD had the following check engine error codes: P0170,P0463, P0130, P0136, P0301, P0302, & P0303. I disconnect the battery, reconnect battery which clear the codes. Now the car seems to have no acceleration power. If I press the gas pedal the rpm jumps up to about 3000 rpm and drops to below 1000 rpm and the vehicle has no acceleration power. I changes the downstream oxygen sensor, the PVC valve and the 2 air filters, sprayed the MAF sensor with MAF cleaner to clean it but
first, you need to find out the exact fuel pressure.
the cat converter may be clogged causing a restriction in the exhaust. with the missfire codes, did you replace the plugs??

The subaru was running much better( It would hesitate a little before accelerating) before I disconnected the battery which reset the check engine light codes. The puffing muffler problem started after the codes were reset. About the plugs; I will remove/check and replace the plugs and then check the fuel pressure if my local auto parts store has the equipment for checking the fuel pressure.
