#708 of 2014 Old Versus New ERG Pipe
Mar 17, 2003 (12:20 pm)
Here is a message I posted about the 3.8 liter engine problem and a response from a knowledgeable person but not sure if the smaller EGR pipe is fixing the problem based on the response:
I have been reading some very knowledgeable postings on the GM 3.8
> Liter Series II engine and needed to know if there has been a fix for

It all depends. If the vehicle is under warranty, it will get a new
lower manifold if it is needed. When the customer has to pay for
it, they aren't real excited about spending 1000 dollars for both
manifolds (by the way, the aluminum lower manifold is cheaper
then the plastic/nylon upper manifold). In that case, the upper
manifold gets replaced and will probably go for another 80-140
K before it warps again.

I'm starting to see the same leaking problem from vehicles with
the new manifold supposedly already in place. Do any of GM's
fix's ever actually work? Some do, some don't.

I don't know the exact dates, but the bulletin specifies that only
95-98 models are affected. But I've seen the older manifolds
on the 99 models.

#709 of 2014 engine cradle ticking
Mar 18, 2003 (8:05 pm)
havent posted in here in a long long time. I have 100 miles left on my warranty and my car has been to the dealer 3 times for the ticking sound when turning the steering wheel in a slow moving parking maneuver. It is scheduled t go back on thursday for a fourth attempt at getting it right. I need help from the group on what the TSB # that refers directly to the engine cradle/rack mount brackets that suspect is what it is in my case. Teo if you are out there I remember you were particularly knowledgeable on this topic. I appreciate the help in advance guys.

#711 of 2014 HELP! Car won't start -cal err- ?
Mar 24, 2003 (7:43 pm)
Took the car to the grocery store. When we got in to leave, I turned the key and nothing happened. The dials all started going crazy and all the electrical stuff in the car went on the fritz. My FOB no longer works and when I ever I move the key to ON or START, or pull the headlights knob past parking lights, all the dials and displays go crazy. After two hours of trying to figure out what to do (all Tow trucks 2 hrs behind) my wife noticed that the radio display read "CAL ERR". I'm gonna try and get up in the morning and have it towed to the shop, but I'd really like to know if anyone has any clue what I'm in for. Please email me directly in addition to posting. My wife's honda is already in the shop getting A/C repairs that are gonna break the bank. I'm tired of walking!
#712 of 2014 cal err - problem solved
Mar 25, 2003 (7:59 am)
Just in case anyone else is searching for the solution to the problem I described above, the issue was a battery that was on it's last leg. Now that I've got a new battery, I'm good to go.
#713 of 2014 engine cradle ticking by chevyrog1
Mar 26, 2003 (2:24 pm)
Hey Rog, I had the same ticking/clicking nose coming from the front end as well while turning. I got it fixed on the first try. Let me write out exactly what my invoice says as far as a fix. Hope it helps.
"Sub Frame Noise at Weld joints. Applied pentratiine locker to frame. Noise gone"
This also took a 24 hour drying time in which I had to leave it over night and a day and they gave me a rental.
Haven't had the problem return yet.
Anyways, hope that info may help with getting your servcie people to fix it.
#714 of 2014 Clicking from left rear of car
Mar 28, 2003 (2:52 pm)
After the car has been running for approximately 1 1/2 mins, I hear three clicks from the rear, similar to a relay, which is what it probably is, though I don't know which one. I have the same brake rotor problem when braking at 55mph or above. I'll wait until about 35 or 40K (24+ now) and replace them with drilled rotors.
I also had a low coolant light at 23,000, but I haven't noticed a strong anti-freeze smell, but I will monitor it.
I also had the low tire pressure light problem, but overall these are minor annoyances for a very good car. Before computers, I did all my own work except for auto trans. I bought the GM extended warranty because of major problems with another American make, no it wasn't a fix or repair daily. I drove a 1966 Impala SS with a 425/427 w/a rock crusher and won over 50 trophies. I also used it to tow my funny car to the track and used it as a daily driver.
Can't wait for the "SS", if it will be for real. Thanks for listening everyone.

I just purchased an '03 Base Model Impala, 3.8 with everything on it. At lower speeds, 20-35 it seems to have an excessive amount of road/tire noise. Has anyone noticed this? It seems noisy to me. I'll get back to the dealer in the next few days and ask them.
Otherwise I like this car better each time I drive it.
#716 of 2014 roadnoise - t_tookalook
Apr 06, 2003 (2:47 pm)
Roadnoise is really my only complaint about the impala, I did change out my tires to some that are less noisy, which did help a little.
One thing that I have been considering is taking off the wheel liners and coating them with a sound proofing coating (on the inside part) and seeing if that helps. I'd say most of the noise is comming through the wheel liners, maybe some throught the floor and trunk too..
