the car at one time was only getting about 8 mpg after a repair. they replaced a broken spark plug wire with a complete new set and also one of the coils. the fuel economy quickly degraded to about 8 mpg. so i replaced the plugs and they were slightly fouled out. i put in new splitfire plugs and the mileage doubled to about 16 mpg. it should be about 20 or more am i right? my thoughts are a weak spark. the car lacks power and does not miss or hesitate. could the ignition control module or the other coils be bad? could the EGR valve be the problem if it is dirty or clogged? what about the charcoal canister? someone also mentioned the timing. do you time a car without a distributor?
