Krabben,

It's been awhile since I've been on. Glad to see all is coming together. I too put a Sniper on. Nothing but issues. Except the IAC thing, did you have any other issues. Me, it wouldn't work with my Megajolt EDIS crank trigger iginition. (still trying to get right) Put in Distr/coil and wouldn't let me get out the neighborhood. I found a tech to write me a tune and he said i have too much RFI. Fighting that right now. Let me know any good tips.
I use both snipers strictly as carb replacements,no timing control or anything else.Im not a whiz either,so I lessen the problem curve.I know alot of people have trouble with msd boxes with them also.Sniper will tell you everything that's wrong with your car,since it needs things perfect,which the carb didnt care about,lol.
I would visit the Holley Sniper tech forums for searching,but the admins there seem to grow tired of the exact thing theyre there for,so,I would recommend the holley sniper owners page on facebook.There are alot of smarties there for live help,and the techs chime in too.There's also a few guys on there you can download a tune from your unit and send it too them for analysis and program for you.
Also,on the rfi thing,if youve ran all your wires correctly,crossing other wires at 90*,it could be anything else.I know a few guys were buying shielding wrap for the wires on amazon to fix that issue.
I feel while the FI is great,the sniper makes a car less reliable,given all the new electronic bits and pieces that could fail.As opposed to a carb,mechanical fuel pump combo.
For my camaro,it was definetly a nice(although expensive overall)upgrade.For my 67 chevelle,I could go back to a carb with that car and be happy.

Yes, I have also put the tape on everything. I do have a magnetic pickup in my Distributor which is probably the main issue. I have threads all over Holley website. Then with no fixes, I did join the Facebook group and that is where i found the guy i paid for support and to tune the car. It is just frustrating that the techs at Holley say this and that works together and when you apply everything, it doesn't work. If I would of know all of this, I would of went back to a carb. But now I am too invested.

Yeah,its alot.I would think about shelving the ignition stuff and going back to regular with that.It seems alot of the problems come from those "mystery' igniton parts.I would stab a regular HEI in there,and just run it as a carb.Then later,if you wanted to tackle things one by one.
Good luck on it.

So,Ive had this "squonking" in the rear area for about a year now.Started out lightly,about a year ago,on first back up out of my driveway,starting into first,then would go away,until the next drive.
Then it started to do it at random stoplights,on take off.
So I tracked it down to the rear drums,duplicated the noise in the garage,and lightly put on the e brake on take off,no noise.
So I just got my new drums from Rockauto,and rear shoes.
There's prolly only 7K on my car so far,but these were used drums from craigslist I had just had my buddy turn for me and had installed new brakes.
Just checked my new parts for fit,so I can paint them and put them on another day.Prolly when I start the QA1 switch over.
Old shoes were glazed also.New drums are alot lighter than the old stockers too.If I remember correctly,they were off of an 81 the guy had said.
