    Help. Code 334 and low gas mileage. Bad EGR? Vaccum leak?

    For the fuel pressure I didn't check it, but the mustang shop I did and they said it was fine and I also already cleaned the IAC about a month ago when I first trying to diagnose the problem. I live in CA so I do have smog inspections. By scanner do you mean a code scanner? I do have one and...

    Help. Code 334 and low gas mileage. Bad EGR? Vaccum leak?

    So I replaced my EGR sensor with one I had in my garage from a fox 5.0 yesterday so that should be good. I checked the valve and applied vacuum to it and the motor stumbled and stalled out so that's good. I also checked the vacuum line to the EGR and it checked out good and I got no vacuum at...

    I have a 95 Mustang GT with 110k miles 5 speed, 2.73 gears, 295 rear tires, and only mods to the engine and exhaust are BBK cold air intake and off road pro chamber, and it has O2 sensors that are little less than a year old. Ever since I got the car my gas mileage has been about 170 or 175...

    Is my IAC bad?

    Today I pulled codes again because the check engine light came on for a split second last night then went away. And I got code 157 for MAF sensor fault for low voltage and code 158 for MAF sensor fault for high voltage, and code 116 for engine coolant temperature higher or lower than expected...

    Is my IAC bad?

    Thats the exact same procedure I tried when I first reset my base idle and it didn't help. I'm thinking about just taking the car to shop so they can hook it up to a diagnostic machine so they can tell me whats wrong.

    Is my IAC bad?

    So I replaced my distributor because I read some other threads that had this problem and it fixed it but no luck. I still don't know what could be wrong. The car is also getting bad gas mileage as well. Also when using the power steering when the car is idling the RPM's drop significantly and...

    Is my IAC bad?

    So I found out my IAC was still good. I unplugged it during a cold start and the car stalled out and died. However I'm still having idle issues and the car is eating a bunch of gas. Right now I'm at half a tank and I only got 66 miles. I've already done a base idle reset and the car is idling at...

    Is my IAC bad?

    Is my IAC bad? (update: read my last post) So lately I've been having some surging and idle issues with my 95 Mustang GT after doing a tune up a couple weeks ago. I've already cleaned my MAF, IAC, checked the TPS, reset the base idle, but it's still surging. Today I unplugged the IAC with the...

    Idle Issues and Stumbles in low rpm

    A couple weeks back I did a tune up on my 95GT with new plugs, rotor and cap and MSD street fire wires. Well it started running like crap after that and had a surging idle, bad gas mileage, and wouldn't idle right. I found out the MSD wires were touching the headers so I changed them to the Ford...

    Suggestions on exhaust for a sleeper

    I have a cat less pro chamber with regular magnaflows and it's pretty quiet at idle, but when you get on it sounds like a nice exotic growl? don't know how to explain it but it sounds pretty good like a high end sports car.

    Just bought a 95 stang and had some questions

    Ya I'm planning to get rid of it but the previous owner put some horrible glue behind it on the a pillar to mount it. Ya no cats or mufflers lol but it gets everyone's attention including cops which is why a new exhaust system is going on with my tax refund lol.

    Just bought a 95 stang and had some questions

    So I just bought a 95 gt 5 speed with some shorty headers and straight pipes and 3.55 gears and a BBK air intake installed. The previous owner said it had bad 02 sensors that needed to be replaced and I figured that was the case because I've been driving the car and I've been getting the check...
