Well Just recently I replaced the plug wires, and air filter cause it was about that time. The filter was pretty gross. Well after I did that I just went cruising and I could instantly feel the difference. It had gained a noticable amount of "gitty up" if you will. things were looking optimistic. The following day me and a co-worker installed a tach. Well for some reason (after the install) whenever I would get full throttle or take it around about 3k rmps the engine would start to bog down. I didnt get it.
So i took it to a local mustang parts store and the guy said 'lets disconnect this bad boy". Ok problem solved. But why was it doing that?
I also noticed that after we installed the tach, my car was back to feeling sluggish again
On top of that, my car bogs down and oftern stalls when accelerating from a stop. In order to get to about 10mph you have to VERY slowly step on the gas. Its becoming an art form. AND on top of that, my car when cold, NOW needs to be choked when starting it up. Sometimes when it is hot too. It has NEVER had to do this before. Even during the winter, I would start it up on the FIRST crank, give it a couple good revs and be done with it.
This is very frustrating as Im sure yall have all been there. Im sorry for the long post. Also, thank you to those who took the time to read thru. Any advice is GREATLY appreciated. I relly want to get this running normally again because my parents are also getting frustrated and want me to sell it
