took it to the stealership

[bboylobo]

I finally gave in and took the stang to the stealership for a diag. They found coilpack on cylinder 7 is going bad. Apparently the coilpack has a bolt or rivet that hold it in the intake. Its broken and just spins in the intake. I think they broke but i cant prove anything

Anyway i was wondering if there was a way to fix this without replacing the intake. And if i do have to replace the intake, should i just stay with the stock PI or upgrade to another like the typhoon. my IAC apparently is going bad too. Should i buy the entire assembly or is there a cheaper way to resolve the iac shutting my car down occasionally



Thanks guys

can helicoil it. I have a 98 been its been converted to use cop's. I made the wires to short the #8 cylinder and can't bolt it down, havent had any problems yet. plan on fixing it one day, but it should hurt anyhting not having it bolted down until you can get it fixed..

Can Helicoil? Have any more info on this.

how do you figure replacing the intake is supposed to fix a bad coilpack? Maybe I'm not understanding something, but it sounds like 2 different issues - a bad coil, and some stripped threads. Either way, nothing I'd call extravagantly expensive.

 

[bboylobo]

well look at it this way. They dealership wanted to charge me 500+ bucks to fix it. apparently the bolt that secures the coil pack to the intake is stripped inside the intake. IE i doesnt come out of the intake witch continues to hold the coilpack to the intake. The coilpack is bad too. They did i diag and found that cylinder 7 is not sparking and its related to the coilpack. im guessing they wanted to move the coil to see if the problem would follow the coil but when he tried to remove the coil, the bolt stripped in the intake. im goanna look at it today and see what the damage is

Interesting... coil over plugs? for which plug? 7?

The rest are fine?

Well whatever you do dont pay 500 for them to put on a stock intake!!!! You can buy the trick flow intake for less than 800 and install is easy.

Everything that breaks is just an oppertunity to improve your car. Don't waste money on stock garbage if an upgrade isn't that much more.

Yeah, that makes sense lol

I'm not saying don't take this opportunity to put on better parts. It's just the OP already has the mindset that his car isn't worth spending ANY money on. He's just going to cobble something together for now. I'd predict in a few years he'll be telling everyone Fords are crap because his Mustang was slow and never ran right.

i love my mustang. ill never say it was slow lol.

i had to snap the coil pack out of the intake. it left that plastic nub with the bolt in and i just replaced the coilpack and the IAC valve and i am back in business. It runs great and idles perfectly i still have to figure out a way to get that nub out and properly seat the coil to the intake. im thinking about just getting an after market intake later on to fix the issue all together. Unless someone has a good idea on how to pull that bolt out the intake. it just spins in place and doesnt want to come out. i think im just goanna take a dremel to it and call it a day. thanks guys

Damn there is so much misunderstanding and miscommunication in the thread!

The bolt that holds down the coil pack is stripped in the intake! And coil pack #7 is bad. The dealer is recommending replacement of the coil pack and the intake. Maybe better to DIY a TrickFlow intake...

I have bought new coil packs they are $49 also if it is not being held down properly that may be all that is wrong.

If it was me I would look into fixing the stripped bolt myself. Perhaps the metal bushing in the plastic intake can be glued? Or tap a larger bolt in there. Then I would use the procedure in the Haynes manual to test the coil myself. If the coil was bad I would replace it. Total cost would be between $0 and $51.

As for the IAC just clean it and if it continues to cause problems replace it yourself with a part from the parts counter.

It is common for that bolt to strip and it is common for the IAC to fail.

I had a similar problem to what you are saying, though i had it related to a fuel rail bolt that would spin, but not come out. I used a slide-hammer to get it out. After that our situations differ, but I think helicoil would work in your case.

So, to the OP, were you getting a Code, CEL/MIL?

Mine's running like carp and it's frustrating. Well, i wouldn't say carp, but it idles funny, has a misfire below 1500 RPM, but runs fine WOT at any rpm.

The only things left I can think of to replace/check/fix are the coils.
