  1. 2005-2010 V6 Mustang Tech
    Hey there guys! I'm new to the Mustang scene and am working on a project v6 Mustang. Currently I'm getting a few codes on the car all having to do with it running too rich. The codes are: P0175 P2198 P0175 The symptoms are the car overall bogs while accelerating, but if the throttle is pressed...

    i have a 1994 base model 3.8L v6 mustang that has been running extraordinarily rich for some time and I've dumped all of my money into fixing it and i still cannot figure out the problem. i have replaced all 6 injectors, i have replaced the air filter, i have replaced the fuel pressure...

    Hey all, My 2006 V6 is running the BAMA 91 Race tune. Recently it has been throwing code P0175 - System too Rich (b2). Now, I know with the race tune they disable the rear O2 sensors, however this still leaves the front two operational, right? The guy at BAMA said I need to try swapping the...

    i have an 89 gt with a few slight mods. it has a cam, cold air intake, msd coil, 3 row radiator, and an electric fan. this past week I had my new exhaust put on. it consists of mac 1 5/8" long tubes, 3" catless h pipe, and 3" cat back. Before the exhaust was put on, the car ran perfect. after...

    I just bought a '92 lx 5.0 hatch today, and I believe it has a vacuum leak. I've been told to spray carburetor cleaner around possible leak areas to try and find it. I haven't been able to locate the leak, but it might be in between the upper and lower intake manifolds. Right now, the car runs...

    hi guys, im having some trouble with my 96 gt 5 speed. i just replaced my catted h-pipe with an o/r h-pipe because my car was studdering and losing power randomly. i had a check engine light saying insufficient flow or cat below threshold (i forgot), anyway i figured my cats were clogged. after...

    Hi guys im new here and today my check engine light came on. I bought a stack racing plenum from american muscle and put it on and this codes came on and called americanmuscle and they said the codes came on because i needed a tune. I bought a sct tuner and the codes went away for a day then...

    I purchased a 91 mustang 5.0. I have been having so many issues with it wish i didnt buy it. Anyway i keep getting code 41 and 91 so i bought a a/f ratio gauge to see what its doing. I hooked it to the passenger side o2. When i first start the car it sits on ideal but after 1 minute it spikes...

    I have been struggling with my carburetor for a year now and want to finally get the issue resolved. The carb was professionally rebuilt twice but each time it went back onto the engine, it seems like it's running very rich. Like to the point of me having to change my shirt after driving it...

    i have an 02 gt with no cats, h-pipe, flowmasters, 75mm throttle body, and cold air intake. here is the problem, the car will randomly die at idle but it will start right back up, also sometimes ill start the car and it will make a loud popping sound (almost like a back fire) and then die but...

    Hi guys. I'm new to fixing cars let alone my '88 mustang GT. I was changing the valve cover gaskets and after the upper plenum bolted back on (as dumb as I am) I forgot how the vacuum lines went. When the car starts runs REAAAALLY rough and is running extremely rich and after a minute or so...

    My check engine light came on and my OBD II said it was an Oxygen sensor heater circuit malfunction. I replaced the sensor and the light came back on. I ran the test again and it said Oxygen sensor stuck rich. Did i install it wrong or do i have a bigger problem.
  13. 2.3L Tech
    So I just recently got my car running after replacing the map sensor, and it drove well last night. However this morning when I went out to start the car it ran fine at idle, but when I tried to rev the engine it sputtered and almost died. After turning the car off and going inside for a few...
  14. 4.6L Tech
    Ok I've got the notorious backfire/sputtering problem and until I can get to the car this weekend to check some of the easier stuff, I thought I'd get some feedback for the specific situation I'm seeing. Basically since I've bought the car a couple months ago it's done the backfire pretty...
  15. 5.0L Tech
    so another problem with the mustang its running really really rich where it makes your eyes burn and the only way to start it is to give it alot of throttle after 5 seconds or cranking it also has a high idle. the first startup its fine then if you turn it off and try to start it it will be...
  16. 5.0L Tech
    My 5.0 is getting a nasty 10 mpg... I am pretty sure it is running rich cause I can smell it and if I rev it up past 3 grand and then let off I get some popping out the exhaust (sounds like small backfires). The timing is somewhere between 10* - 14* btdc... What can I do to get the car to run...
  17. V6 Tech
    I was wondering if it was possible to make my V6 run a little richer without buying any tuners or anything.
  18. 4.6L Tech
    It does have cats and they look smaller than what I would have expected? It also has an H pipe not an X pipe. If its running rich or has weak spark what would be the most efficient way of dealing with that? I dont have a tuner or anything. Maybe plugs and wires? It does have 80,000 miles on it...
  19. V6 Tech
    Hey thanks to everyone answering all my questions, I have another one now lol. When I first drive my car in the morning it feels like it has maybe 30-40 more hp. Is that because it runs rich until it's warmed up? Is there any kind of Tuner out there that can make it run that way all the time...
