ignition upgrade

As always im looking for ways to work on my truck, and i would like to take a stab at gas mileage and maybe some throttle response.

I thought about maybe a new performance coil? What else could i do? MSD box or anything like that? More than likely a waste of money but thats why im asking. Thanks guys. (its a 94 f150)

That's what I was just looking at today. I tuned up my 300 and pulled my msd coil from my mustang *waiting for new heads and cam and other goodies*... I just wanted to see if maybe the coil would help the mpg out a bit. Idk what else... I have to get rid of that horrid filter box set up. Who knows.. I don't tend to drive my truck like I stole it. We'll see huh. - nick

that "horrid filter box set up" is actually a very well design. leave it alone...

im running a Crane ps-91 coil with taylor wires and cheapie autolite plugs gapped to .055 and it seemed to help the idle a bit and add a hair more throttle response. i didnt see any change in mpg but i dont expect to get uch anyway.

MSD im leary of, i perfer crane.

I've beem running an Accel coil and 8mm wires for over a year and recently replaced my TFI module with the Accel one as well. Openned the gap on my plugs to .055 as well. Excect for an intermitant vacuum leak (EGR related and working on a remedy) I'm running smoother and have had an increase of 1mpg to boot.

Mileage increase could be from me not pushing as hard when merging on highways. But I'm getting to 65mph in a segnificantly shorter distance than I did prior to these changes. And I'm holding power better on grades as well.

IMHO, ignition upgrade is one of the best single things one can do and they don't have to be very expensive. Try gofastforless.com for some good info. A number of outfits make ignition products that will work on our engines some of which have been already mentioned here.

SR_C: If you have those small, hard plastic vac lines...they can crack. Or it might be within the EGR valve itself.

u raise a great point Harte3, those small plastic vacuum lines are horrible once they get around 10 yrs old. i bet A LOT of peoples driveability problems come from those.

u got me thinking now...perhaps one day next week ill replace all those vacuum lines with regular rubber hose...because i have a CEL that i cant get rid of LOL.

im gunna check ou that site u mentioned also...

oh, we upgraded the igintion on our 66 Fairlane GT from the old points and coil to a Crane electronic conversion kit and high output Crane coil and it made a world of difference so i can definatly agree with ya.

i just replaced the stock coil with a Crane PS-91, plug wires with Taylor wires and normal cheapie autolite plugs. the control module is ok as is. u dont need to go with a box or anything either.

try to look for a cap/rotor with brass contacts.

I've got a seperate thread on the subject.

Short answer is that I broke one of the studs that mount the EVP sensor so it no longer seats properly. Leak didn't exist before this. So far so good on the old vac lines, which a little startling considering the mileage.

Back on topic:

Sn0wMan, until your really pushing things MSD's aren't really needed with these engines. I upgraded my coil/TFI/Plug wires out of personal preference not need. OEM parts will get the job done reliably. The Coil and TFI that were replaced had over 280k on them.

I didn't get $200 worth of improvement from the MSD box and coil. My plugs don't seem to last as long anymore. Modern (i.e. made in the last 20 years or so) don't need the help that the older ones did.

If you want to do a good tune-up. The cap and rotor will last 25K or more and wires are life time.
