Help needed, engine problems after intake and exhaust install

[2002GreyGT]

Ok I hope someone can help me figure this out so here it goes.

I installed a full intake system (tunableinduction.com) all the way to the TB and a MAC Catback exhaust (from here) Thursday. Everything was running fine until today.

Left the house this afternoon and got about 2 min from the house and wsa sitting at a light. As I gave it gas (not much normal driving) the car did not want to move and there is this popping noise comming from the engine. At idle speed you can't really hear the popping noise until you open the hood.

If I give it any gas the popping gets worse and louder. There also seems to be some hot air / exhaust comming from the back of the engine bay when I give it gas.

I checked the oil and everything else and all seems ok to me. I disconnected the POS battery terminal and I am letting it sit to reset the computer.

Any other ideas?

was it a popping or tapping..hot air coming from the exhaust might be a gasket leak

When you get it resolved, please let us know what the problem was.
How do you like the tunable induction setup? From what I have read, it is the only CAI that actually offers any peformance gains.

Its a mix of ticking and with gas it kind of pops.

Sounds almost like a overgrown chainsaw sort of.

I guess I'll try to find a shop open Sunday.

OK that intake you added came with its own MAF correct? Sounds to me that you are having a MAF flow problem. If you have your old one i would put it back on or inspect the one in there for flaws or dirty!

Sounds to me that you are having a MAF flow problem. I would take it out and inspect it and clean it to make sure it did not get some dirt on it.

The MAF did not get replaced. The kit I put on just replaces the pipe between the TB and MAF and then routes through the fenderwall. The stock MAF is there.

It seems like all the air is comming from around the coilpack in the rear on the passenger side. I just had ford replace the spark plugs and a bunch of other work not too long ago. Maybe the messed up on that coilpack / plug. Sound Plausible?

Of course I am at my gf house and have NO tools and I live 45min away.

Luckily ford is paying for $100 of the towing to my dealer so all I have to pay is $6.

Crossraods ford in Cary, NC SUCKS!

So got off the phone with Ford service, and they are saying the need to replace my cyclinder head, etc since a spark plug was blown out!

Funny part. 2 months ago and about 3000 miles I had ford repalce my spark plugs!

They said that they are going to replace everything under my extended warranty.

They gave me an excuse that this is commong on 5.4 / 4.6 engines from ford. Can anyone attest to that? I never heard of it. Sounds like some BS to cover up some ****ty plug cahnge job.

I requested to have all my broken parts back after they work on it and they refused since they need to return them to ford, so I requested to have them left for my instpection. Lets see what happens. Cause if that spark plug is Cross threaded my warranty should not be charged as it was there BAD WORK!

the spark plug blow out is a 50/50 in all cases... it seems to happen a lot to the 4.6 when compared to any other mustang. something with the head design and the way the socket is threaded that makes the spark plugs back out. i check mine every 20k to see if all is ok. the ticking could either be there plug blown out, or the leaky gasket for the headers.... either way, when you pick up the car from repairs make sure they bring out the old parts and SHOW YOU what went wrong, and see what all was replaced. some dealers are absolute gems, others will do anything in their power to bend you over.

the only reason they wont give you the parts its because of the warranty and they need too have the parts checked out to see what went wrong but when you pick it up none the less ask them to see the parts either way

WIll they be required to do a compression test after they install the new cylinder head?

I should be able to get a copy of that report too?

I am going to bring my digital camera to take pics of all the parts when I see them. I also caught them in a lie about my cruise control, see my other post about cc not turning off when I push in the clutch.

I am currenlty writing a letter to Ford Customers Releationship Center with descriptions of all the poor work and all the proof from other shops, and how I got jerked around by this dealer. Maybe they will lose some of their status?

 

[03ghoststang]

not really they will just get chewed out by some big shot in the shop and they will get stricter on doing a road test and making sure the problem is completely gone i know because at the dealership i use to at a tech in my group didn't road test the car and it came back with a bigger problem that came from the original one

edit: they should do a compression test, but don't really know how things work at ford dealerships i know that at the mercedes on i worked at we would do it for those kind of problems.
