My '92 EX, auto has been getting around 15mpg for quite a while. I've read the forum for quite some time and want to thank all the contributors for the very helpful info that I have learned.
This is what I've done so far for maintenance and to correct the problem:
Replaced O2 sensor (NTK)
Cleaned egr valve and egr ports
New fuel filter
New plugs and wires (NGK)
New distributor
Rebuilt TCU
Compression test (highest to lowest are within 10 percent of each other)
Seafoam in the gas tank
I have gotten a code 43 since the problem began and still do. The car runs very lean. Plugs are white after 1000's of miles. They are all the same color. Car hesitates, esp from a stop. It is so bad that with a/c on it will barely move from a stop. It also occasionally pops through the intake.
I am really at a loss as to what may be the problem. I'm thinking maybe FPR or ECU but I hate to continue throwing parts at the car. Any help would be greatly appreciated!
