dick32	1998 Toyota Camry 4 cylinder codes P0125 and P1135. P0125 (closed loop fuel ctrl) and P1135 (manufacturer control fuel air metering)and then P1135 will show again with a(pending). Have replaced thermostat and plug wires was told dirty MAF. Toyota told me no MAF on that model uses a MAP cleaned conn contacts on that and o2 sensor on Exhaust manifold which Toyota also said could be the problem. $420 to replace thats why I did not replace yet. Erased codes, P0125 reappeared within 2 miles and P1135 within 30 miles and P1135 again with pending after about 40 miles. Car runs fine. What do you think?

Fuel metering code I try and look up th troubleshooting steps .

First things to look at are the duct work going to the intake I'm gusessing the mixture is not right either air leaking or the the sensor for the fuel system, or the fuel system itself is weak. Check fuel regulator.

These are parts you need a gage to check but the regulator is on the fuel rail with a diapram and a small vacuum hose attached pull it off to check for fuel. Other than that I have to check the steps .
