I put the timing light on my Mustang adjusted the timing to 10° it ran light total crap!!! Let my dad adjustedit runs alot better just still can't runt full throttle after he left I check the timing it was 30° advanced.... Next just for shits and giggles I unplugged my MAF sensor and drove it... it launched the hardest it ever has since I've owned it plug it in runs like crap ANYONE HAVE THOUGHTS ON THAT?

This is the type of gauge I'm talking about. You can use any gauge as long as it's a vacuum gauge, but these kinds are cheap at harbor freight. Plus you can get a one person brake bleeder kit for them because it's also a vacuum pump.

What mass air meter you running? Do you have someone else's that you can try on your car? Can't remember also, but did you check your TPS not only at throttle closed and open, but through the whole range. Open it slowly and look for erratic voltage changes and not a smooth increase.

Well all is fixed it was my MAF sensor it must have been extremely dirty I sprayed clean in it plugged it back in and it runs like never before ... Also installed electric fan for under $70, E3 Plugs $52... and swapped the 160° out for a 180° the guy that owned it before I did had the 160° in it

I have a stock mass air. I cleaned it up. same result
Put a vacuum gauge on it. It's a steady 18-19, jumps up to about 22-23 when I rev it up.

I'll take 7... I heard if you don't run one plug, your car will lope like a muscle car.
