Im posting my issue on this site as well to get as many opinions as possible.  I dont have a FP gauge yet.  Please help.  I havent done any step suggested yet b/c i want to get all the input i can first.  Thanks guys!!

First, Glen sells the correct parts....if you want to post a pic of what you bought, we can tell you if it is not the right coil pack.

Second, the coil packs are not particularly sensitive to brand, but, I will not use anything but a GM module as it seems to be very iffy when it comes to proper functioning.

third, coil packs/modules usually fail completely and miss badly under boost, but, often will still run okay in normal driving.  If I understand correctly, yours is missing at cruise.

If the coil ohms out properly, and all three coil packs are firing a blue spark, I would look elsewhere.

bad plug wire, gummy injectors not spraying properly, fouled plug

If it misses while running at an idle, pull the injector clips off one at a time, and see if there are one, or more, that don't make much difference in how it is running as it is removed.  Be sure to note those cylinders for further discussion.

Hey steve, thanks for the reply. Everything is actually fine while cruising. Under acceleration is when I have these issues. Sorry if the post was confusing. On another note, just went outside to check it out b/c I haven't had a lot of time with the car, and found three different locations in which It was leaking fuel.

I checked Glens site...and all I see are coil packs for our cars...so I'm not sure what your referring to as FWD...unless your mechanic tried using a series 2 coil pack. I agree with Steve about only using GM modules...as I've seen more than one of the guys up here have less than desirable results with aftermarket modules. Gummed up injector(s), a plugged up fuel filter...or a weak pump could all cause the symptoms you're describing. You really need to know if your FP is rising with boost...and some SM numbers would help.

Posted the same time as you did Phil...and just saw you have fuel leaks. Fix 'em...and take it for a quick drive and report back. The engine might be starving for fuel when you lay into the loud pedal with the leaks.

[Steve Wood]

find a way to check the fuel pressure as well...

[Steve Wood]

ALSO...ohm the coil packs and tell us if they all are in the correct range   11-13 k ohms

[phil_long]

Will do gents.  My next response will be the resistance of the coil pack.  When the mechanic mentioned the FWD coil pack i scratched my head b/c i spent quite a bit on the units i purchased from NOS4GN.  The quickest thing i can do is ohm the coil pack.  Thanks for the responses and stay tuned.  I can also post some SM numbers.

[phil_long]

Also forgot to mention that the SM shows a code 44.  havent unplugged the ecm wire from the battery to check and see if it clears permanently or if it'll come back, but i do feel like i should mention it.  I think code 44 is a lean exhaust.

Code 44

[Steve Wood]

might have mentioned that right off the bat.....

what are the mafs, and O2s at wide open throttle...and again, the fp?

[phil_long]

I havent went WOT b/c im afraid something bad will happen.  Lol.  Im in between moving because I just purchased a house so it'll be some days before i can actually get to driving it.  Gonna fix the fuel leaks as well.  My cousin Charles let me borrow his laptop that has direct scan on it.   havent hooked it up yet either.  Should be able to get you everything you need from that, yeah?  I'll be in touch guys.  Again, thanks for the replies.

[Steve Wood]

good luck with everything...y ou and Charles are always moving, it seems to me!

The 44 makes it sound like it is not an ignition problem to me.

Get a FP gauge stat - they are cheap and worth every penny.

[phil_long]

I can purchase a FP gauge from anywhere right? And Steve, this is my 1st and last move!! Lol. I'm excited. I'm still in the same area though. Charles on the other hand definitely moves a lot.
