My advice is run a code scanner first before you get the coils!.. Make sure that is the problem, would hate to see you throw some cash down and still have the same problem!..

I cannot speak for ALL SVE parts but I know that my SVE springs are in fact FRPP springs, paid for the SVE name got the FRPP part, just something to think about....

If you know someone with a wand-type coil tester and an advanced scantool see if you can use their tools.. I thought I had a bad coil but I tested mine with a snap-on MODIS and my coils were all within 2k volts of each other, which is fine considering the innacuracy of the tool. I know its a long shot, but coils are expensive and I know a lot of us have mechanic friends or the such.

I have a scanner and it finds nothing, I'm 18 in a city of hardly any people with an intrust in cars so I don't have many resources. I figure I might as well get new ones sence the ones on now are stock with almost 90k miles.

You said your car had almost 90k have you checked the fuel filter and maybe could be dirty injectors

The whole point is using the conductive wand. You put it on each of your coils and it shows how many volts they are firing at. Just checking codes won't do anything. But, it sounds like that won't be an option so you may have to try for coils. I'd replace fuel filter and use Motorcraft copper plugs and see if you get any difference first though.

Re: SVE vs Steeda Coil on Plugs

did you change plugs already(recently)? assuming YES, i've seen in several threads previous that the general consensus to stay with stock, although there are some fans of the msd blaster cop's. i was thinking of upgrading(changing) mine too, but not really sure if any performance gain would be seen?!

---------- Post added at 06:38 AM ---------- Previous post was at 06:32 AM ----------

oh; just saw you did the plugs... a long time ago?! like how many miles? might be good to just take a look at 'em, and re-check gaps anyway.

p.s. if you like accel, those are about $182 on amazon

Is there a way he can test his injectors? W/90k, you'd think that could be a trouble spot.

If it was me, I'd replace the COP's w/that mileage. Before that, I would try to isolate the problem.

Also, if this only happens at high acceleration, maybe your fuel pump is getting weak.

It did it before I changed spark plugs and fuel filter. I guess I can pull the plugs tomarow and post some pics, I get paid Friday so I'm can't buy anything tell then lol.

An other thing is when I got my bama tune it causes my car to ping if I run regular gas on the 87 tunes, so i have been using 89 octane gas and it seems to no do it as much but if the car lugs at a low rpm it does it, this causes me to think some thing is wrong some were.

Re: SVE vs Steeda Coil on Plugs

yup, pinging with the bama tune... had the same problem when i installed mine. there is something you can try, and that is adjusting (taking out some) timing with the handheld.

i currently run my 91 tune with 93 octane gas, and this combination seems good ( i did have some pinging here too, took out some timing, and it was better; then went back to default timing, and still running good, so maybe some variance in fuel quality?!)

how'd your plugs look, is the gap spot-on .054, and did/can you change your fuel filter?

Well they are in, I just finished and drove it around the block. It ran just like normal and I didn't feel any difference. I didn't put my foot in it so I can say any thing on that subject yet. The idle is still rough so i decided if its any thing bad I will just have to wait for it to die, I'm done hunting. I will go out for a more agressive drive tomarow.

They are doing fine, it was not my problem but they seem to be doing fine. I figure up ny mpg every time I fill up and I'm getting about .8 mpg better now. Nothing big in the performance area though.

I'm hunting the same problem, but i probably do need to replace my COPS and plugs. Just gotta get my money first. And figure out whats the best brand

I have decided if its not broke, don't try to fix it. My car idels rough and I was trying to get it smooth. Now I'm just going to save my money and if something goes wrong fix it then rather the replacing something that's still working fine.

Ive always had the idle hunt issue. But now if i put the car under load it starts missing, no codes or anything. Im not sure if its a fuel delivery problem. So im replacing the fuel filter this weekend. I dont believe its a plug problem because it only does it under load. So idling its not missing

Pity, I read all the posts. No one has suggested that you re gap your plugs to a closer tolerance. Bring them to minimum tolerance. If that don't work, cylinder heads may need a comp test. Think about it, it's a mustang. It runs hard. Just my 2 cents.

Heck, I put mine at about 35 I think, but my heads are tired. Time for PIs. 50's way too wide.

So what are the drawbacks to reducing the gap, if there is any?
