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 this had no effect on the car performance. Any ideas what I should do next.
