A month ago I got a check engine light and the engine code indicated
insufficient catalyst. I was putting off reparing it because I just
got thru paying $1500 on a new intake manifold, and several other
problems.
Now there is an exhaust leak and the noise sounds like its coming from
the catalytic converter. I guess it's time to pay up again. It appears
that there are two catalytic converters. Do they both need to be
replaced?
No more Fords for me! |

Getting off topic here but those COPs cost about $50 aftermarket but
the tech probably only spent an hour changing them, definately no more
than two hours. So $500 is not too bad. What I want to know is how
did the service writer convince you that all your COPs went bad at the
same time? Was your engine light blinking? I've only seen them go one
at at time on any of my Ford vehicles. It's not Ford's fault their
dealers sometimes gouge customers, all car dealers do regardless of the
brand.
All cars (most) have problems eventually. I think your problem is the
dealership taking advantage of you not the vehicle.
Regarding your insufficient catalyst, just taking a guess here, some
catalytic converters (maybe all I don't know) use oxygen as the
"catalyst" to break down the pollutants in the exhaust gases. The
oxygen is delivered to the catalytic converter in the form of fresh air
obtained from the air box (where the air filter is located). When one
of these hoses breaks, little or no "catalyst" is delivered to the
converter. Now it sounds like you have an exhaust leak, I'll say
because one of the rubber hoses is probably broken and the noise got
your attention. Could also be a metal tube that rotted and broke. I'm
no expert but I've fixed catalyst plumbing before. |

$1500 for an intake manifold??? Someone saw YOU coming!

Insufficient information. What engine? What symtoms, other than a
"code?" How many miles?

Sorry I didnt see all of your response.
The car has 138,000 miles. I am wondering where the exhaust leak is.
I cant crawl under the car to see the leak. Doe the cat have a gasket
that could be blown?
Again, the 1500 wasnt for the intake alone. The car had problems all
at once and its happening again. It may be time to dump the car
because its costing alot to repair

It was much more than intake manifold. It was an entire set of COP
Coils @ $60 each + labor, = aprox $500 8 Spark Plug, Ball Joints and
Tie Rods. All added up to about $1500. This car is areal toilet.

You are probably right abut the O2 sensor, but I found the exhaust
leak this morning. There is a leak at the joint just aft of the right
catalytic converter Looks like a tough job to get the bolts off and
replace the gasket. It's also a hassle to get a mechanic to replace
the gasket only. They will want to burn off the bolts and replace the
pipe.
I'd rather not do that because replacement pipes are junk.
As far as COP coils, there were several bad ones and so I had them
all replaced They eventually fail. The car runs lousy when they fail.

There's NO rule of thumb that says that you must replace them as a
pair. BUT since the y-pipe has to be disconnected to replace one
converter, good sense would dictate that you might as well do them
both.

The intake manifold started to leak antifreeze. The mechanic thought
it was cracked. When he removed it he found that the gasket was
cracked. He relaced it with a metal reinforced intake. The metal
reinforcement is near the alternator mounting location.
If yours strat to leak, make sure it's really cracked before you go to
the expense of replacing it. They do have a history of catastrophic
failure at the alternator mount.
