Shuddering engine...UPDATE July,1

I see, I've been away a little. If it's 1 cyl. comp. test will tell you something. Don't use them 24's I sent back to you cause 1 or 2 of them are f'd. It sounds to me like a bad injector. Need more info to help. I got tired of used inj.'s, had to many issues with them,like yours. Bought venom ones, good price,so far no complaints. Hopefully it will be that easy.

:poke:Not meaning to be rude, but killing each cylinder one by one would have most likely pointed you to #8 dead miss or not. Now that you have replaced plug wires, clean that plug and swap it with #7. If the problem is gone, it was a plug wire. If it changes cylinders, it is the plug. If no change, it is either injector or cap. Not sayin it can't be a valve, but that is not likely. You don't have a whole ton of miles on those valves, and I would assume you have not had any overheating and have not been terrorizing Ardmore like a teenager that just got his license. Glad to see someone else is using Summit brand equipment. I don't believe they make their own stuff. I think they have a deal with other companies to make good quality stuff at a lower price.

Not to hijack, but Summit was real nice to me when I bought my x pipe and Flowmaster kit.

Vinnie, I have a set of 24's, from a Mark 8, pulled them myself. Let me know if you need one of them (or all 8)....

My injectors don't have the typical pintle caps. They are a different style. I'm HOPING that a screen on the top is plugged up. I have three replacement screens, and about 40 on the way.I will be posting whatever I can find out, or not find out. I'm still listening to all I can from you guys.

i ordered a brand new fuel tank for the Sport, the rebuild kits for 4 sets of injectors are in route, and once they get here, I'll install the new parts, then enjoy. It will be nice to have a new tank, not used. It was a very fair price, so, I pulled the trigger.

Did you track your problem down to injectors or tank??  Sorry, I forgot where you were at on this. LOL

Apparently there's rut in the bottom of the fuel tank. The tank is not original to my car. It's allowing some super fine "rust dust" through the system and into the injectors, so, they will be cleaned and new filters installed in them all once the kits arrive, new fuel filter...again, and new tank with 5 gallons of gas (to test everything before I add another 17 gallons). The tank was $94.00 shipped, so, I could pass it up. Seemed like a great price. It took money that I wanted to use for other things, but, the other things for the Sport don't really matter if she's not running good.

I saw the  in the top of my fuel injectors, and figured it had to come from the tank. Pulled the pump, took a long look, and yep......rust in there.

OK you nailed it. We went through this a few years ago!!!!!! Your fuel in your area is spiked with to much alcohol. It has the potential of loosening rust in storage tanks and delivery trucks. You are going to have to find a different station that has pre-filters and or come up with a better filtering system in your car. That RED RUST STUFF is coming from area truckers underground tanks and or a combination of both. Someone down the line has a tank or tanks that are being deteriorated. You need a finer micron filter count on your car. We went through this a few years back when the state mandated alcohol blends. This sorry to say if it is what i think will take a couple of months or years to clear up. All stations are now required to have snorkels and all delivery trucks are to be stainless. Filters on the delivery side must be maintained by the vendors but who knows if they do.  If in fact the rust is getting on the injector screens it means only one thing!!! Your filter is not fine enough to weed the  out. Either way the  in the tank is most likely pumped in and when you inspect you tank that will call the shots. If it is clean and not rusty you have just been  introduced to the alcohol blend nightmare. good luck and find a filter with a greater micron count and if possible double it's size. Good luck !!!

NOTE YOUR ENTIRE FUEL SYSTEM NEEDS TO BE COMPLETELY FLUSHED OUT. The entire thing and dont not do it. That  is in every line valve and regulator as well

Thanks Tom. I'll get all of this fixed and see what happens. Better fuel filtering? Hmmmmmm I wonder how I can do that. Good idea. I do know the tank itself has rust in it. I didn't notice that when I got it (used). The tank in route is brand new, in the box.

Vinny just some info. I know parts are expensive and i know you have kids. With that said i would suggest a SS tank if available. We use them on camaros and firebirds with good results. Or always keep the tank full as possible to prevent rust. I will research some filters for you. Hay i told you you could find the problem. Hay throw those FOR SALE SIGNS AWAY. And stop wining when you have an issue. You nailed it quite well. Now show us in a photo of you tearing up those FOR SALE SIGNS. You did a great job Vinnie. Then again i get flamed when my car acts up ALSO No one wants a busted car.  YOU AINT FOOLIN NO BODY ON THIS FORUM      WE  know you love that car and it shows. Peace My Brother Great job Vinnie!!
