I need some help..
I posted a couple weeks ago about how my 95 GT has been acting up. Whether is cold or warmed up its doing this. Normal throttle just cruising reaches 2500-3 rpms and its driving fine to that point then its like someone cut off half my cylinders! I put my foot in her and she just takes off. Now I cant just drive with my foot to the friggin floor all the time (gas prices haha) It does it in all gears and right near the same rpm! I have pulled my plugs changed my wires and checked out my cap and rotor. I have also tested my TPS and IAC just to be safe. I have a new MSD pro billet distributor on order and my msd coil is not very old. The fuel pump is no more then 2yrs old. I could really use some help guys Im military and I gotta drive to work everyday and I just flat dont have time to screw around anymore. ANY HELP WOULD BE GREATLY APPRECIATED! Im losing my mind with this car..
I bought a new MAF as well.

The fuel pump may be 2 years old or less but I'd do a fuel pressure test anyhow. Just because something is fairly new doesn't mean it isn't the problem. In fact I find the new part is usually the culprit. It's easy to do and only takes a few minutes so you might as well rule it out.

stdyhand I put a bbk 255lph pump in it. To be honest I think I may have went a lil over kill but thats what I ended up with. Im not sure what fuel pressure I should be seeing and should I test it at the fuel rails?

I actually just went and got a new fuel filter, guess we will see once I put it on! Just blows my mind it only happens at or right near the same RPMs. Im not convinced that the fuel filter will fix it but Im crossing my fingers!

It's not just an internet myth mike. I have personally pulled one OOTB, dropped it in the car and had to chase a no-start issue. Which was in fact, directly attributed to the distributor.

Well I hooked my up a lil OBD1 tool I got from the parts store and I got some interesting stuff. Throttle position below minimum voltage (maybe because my TB is aftermarket and i dont have it set right? Is that a possibility?) and I got another code saying HO2S Sensor fault/ lean. sensor always lean. and sensor fault always rich.. What I get from that is I had better get under the car and check some wiring. Then lastly is says that my fuel pump secondary circuit fault. Any one of these could be my issue with the way the car is running correct??
