Hello, I have a 91 Ford Explorer 4.0. Vehicle sat for a year and leaked water down to the computer. Replaced computer and then ran good. However, it only makes it about 15 miles then CEL comes on, loses power, idle ramps up to about 2 thousand RPM on side of road and dies. It’s done it every time I’ve drove it now. The 2 codes that are present are a 95, and an 87. Things I have replaced include: fuel pump, canister purge valve, throttle positioning sensor, computer, fuel filter, spark plugs, plug wires, fuel pressure regulator, water pump, thermostat, fan clutch, and radiator. I also made sure fuel cutoff switch was good. Please help! Any suggestions welcome thank you!!
