well there's your problem sir your A/F is wack! It's supposed to be a virtual flat line sir and it has spikes. And from the looks of it when it does spike, it spikes rich. That leads me to believe your ignition is toast and/or your tune is junk.

Thats what the tuner guy said about the ignition he said the coils are prbly crap. I was only there for a diagnostics check and base pulls no tune. ill be puttn up a video you can actually hear my car getting louder and dieing down then getting louder.

yeah either the ignition is failing, injectors are dumping too much fuel, or the tune is off. guarantee you if you go get some motorcraft coils you'll get your power back.

For reference I had a similar issue when I got dyno'd, the COP's were beginning to fail and between 5000-6000 it started spiking and you could see the A/F dip into rich territory.

his A/F isnt perfect, but its honestly better than i expected.

The only ones I could find (motorcrafts) where the COP's for 68 or 79 a piece..as in each individual COP. Did you convert?

96-98 coil packs tend to run cheeper because they easier to produce and more cars use them.

mtang98 gt · Mar 23, 2011

MAIL ORDER TUNE FTW I MAKE 30000 rwhp I GOT THE DYNO SHEET TO PROVE IT!!!! No i did not convert my car, they are on rock auto for $69.
Do you guys hear what im talking about in my video?

mtang98 gt · Mar 23, 2011

Should i change my plugs too? also could my wires be messed up? Some of the wires dont wanna push down and clip on to the coil packs i have zip ties forcing them to stay on right now

MustangChris · Mar 23, 2011

wait till your OEM units come in. then try your wires... if they do not clip onto the new packs, you may want to buy new wires, as that could be the ingnition problem these guys are trying to diagnose....

OEM wires work well for moderate power. FRPP work well for moderate power and full-bult-on applications... once you get to Power Adders or something insane, you may want to look into a set of premium wires that have gobs of insulation... but for your car, that wont be needed at this point.

Blk97GT · Mar 23, 2011

You say you have 24lbs injectors.....is your MAF calibrated for them or is it still calibrated for the 19lbs stockers? That could be a huge problem right there.

MustangChris · Mar 23, 2011

i have an OEM 1996 GT MAF, OEM 2004 Cobra MAF, and 36# (brown top) injectors for sale.

I'm not trying to pawn my stuff off on you, just not sure exactly what your MAF/inj. situation is. trying to offer you a budget-friendly solution....

mtang98 gt · Mar 23, 2011

I have an OEM MAF, and FRPP 24# injectors not running a blower or anything so i think im okay. Im gonna run seafoam tonight just for shits and giggles to see if it doe anything.

MustangChris · Mar 23, 2011

yes, you should be fine... i just wasnt sure if you went changing and swapping things out... .. ya know? 24#s should work well into the 400 hp range (maybe higher, im not sure.)

BruhBrahBrad · Mar 23, 2011

Is your oem Maf Calibrated for the injectors? I know I had bought my car with 24s and the stock injectors and it was alll bad.

mtang98 gt · Mar 23, 2011

im tryn to see if people can hear what im talking about in the video i posted did you hear how the odd the car sounded?

Yeah bama said they tuned it for the injectors
