    A/C Issue - Passenger Side Cold; Driver Side HOT

    Same issue with my 2009. Passenger side colder than driver's side. Low on refrigerant. Slow leak through the high pressure side Schrader valve. Elected to evac the system - replace the valve and re-pressurize.

    94 Ltd Woes..

    Check the fuel pressure at the fuel rail. Should be around 35 psi. Check for raw gas in the vacuum line on the back side of the pressure regulator. If it's wet the regulator is bad. Fuel filter, spark plugs and wires are also suspect. Listen for the fuel pump whine when you try to start it to...

    Leaking Injector?

    Hi there and welcome. I recently worked on my injectors and fuel system on my 92 Sport. If you have a Haynes manual it is a very good guide for removing the upper intake, fuel rail and injectors. I took me about 45 minutes to remove down to the injectors. One quick thing you can do now is...

    Confirm a diagnosis: FPR &/or injectors

    Update on the idle problem: I pulled the upper intake, re-torqued the lower and checked injectors. There was no vacuum leak. Ended up finding that the throttle body was worn around the butterfly, allowing too much intake air passed it. I adjusted the stop screw and the tps to solve the...

    Confirm a diagnosis: FPR &/or injectors

    Thanks 410. I'm gonna pull the upper intake and check the lower. Probably re-gasket and torque. I'll look over the fuel rail & injectors while I have it apart.

    Injector Size and Type for a 1991 4.0

    The 19# Bosch's are correct. I'm with Billy177 for checking the emissions. Double check the plugs and wires..they make a big difference. I've only had good results with Motorcraft. How many miles are on the engine? You could run a compression check on the cylinders to get an idea of the wear it...

    Same old hard to shift Mazda 5speed

    I had the same symptoms before I yanked the trans out last summer. I had a bad slave, throwout bearing and flywheel. I replaced the clutch with the LUK oem set but put in a new Ford slave cylinder. Make sure the flywheel is within tolerant thickness. Mine had been turned once before and was...

    Oil Pump replacement and harmonic balancer

    A rear oil pan leak has forced me to pull the 4.0 on my 1992 Sport. While I'm in there I'll put in a new oil pump. Does anyone know the Torx size on the oil pump bolts? I'm also replacing the timing set. The manual recommends using a harmonic balancer installer tool when you go back together...
