That would be the best route but if they want to do some sightseeing they might go off the beaten path..

The thought of that scares me. I been trying to find the write up on how to diagnose the HVAC controller but I can't seem to find it again. I came across it on another post a while back when I was having electrical issues, I am stumped now

Just replace the fan if it doesn't blow, its very easy to ...

Hey everyone, haven't been on much lately, but that's a story for a lounge post once all the dust in my life settles a bit...

My current issue I'm trying to correct is that the cooling fans on my 96 SUCK. In traffic with a 180* stat and reprogrammed fans it will still get over 200*. I've noticed ...

I found the thread on replacing a wheel bearing on a 1998 SLE (thanks for the post BTW) HOWEVER one point wasnt covered in the thread I was reading.. Once I change out the bearing will I have to take the car into the shop and the wheels realigned ?

You shouldn't need to have it realigned I ...

Once in while when I turn the ignition key nothing happens. I wonder if the ignition switch is bad??
Could this cause random stalling?

Do you have any auto start on the vehicle because I get the same problems, I have mine in right now because it bucked like you were saying and it said it had a ...

I have a problem with Bonneville it comes up with a random misfire and I don't know where to begin, spark plug, wires, egr valve, fuel injector, Oxygen sensor, Vacuum Leak, coil or Ignition Module? I dont want to throw parts at it and hope it works. What is the most common for a P300 misfire code ...

I was thinking the same check the actuator which you can see if you open your glove box all the way, move the latch holding the glove box in place and it will open all the way up spilling whatever you have in the glove box on the floor. Look in there and change the dial from hot to cool and if it ...

I have a 1997 Bonneville and I have had zero problems with it its the 40th year anniversary SSE and it works great. I had to change a water pump and serpentine belt while I was changing the pump. I wasn't aware that I had to unbolt the motor mount and lift the engine with a jack to get the ...

My battery was changed in May of this year and it has always been fully harged. I have the viper auto starter which would kill the starter as if it was trying to get stolen. Sometimes the when the car doesn't start it doesn't turn over the lights come on and I have good voltage but it wont crank ...

I noticed the security light was flashing on my dash and I didn't even try to start I have a good voltage and new battery. The only thing I can think of is I put a viper alarm and auto start' would the installation of the auto start and non factory security be messing this up. It started acting up ...

well considering if you did it yourself might be around $50-75 probably 100 with fluids and everything on the cheap side. But talking about a shop doing it, you looking at about $100 an hour for labor, parts are usual double priced (at dealerships, probably normal price at local shops) then at ...

sounds like you had the lower intake manifold gasket crap out on you, which dumped coolant into you oil, and was probably also going into cylinder 2. Milky oil means coolant is in there. Changing the manifold gaskets arent very hard or expensive and you can find write ups on this site to guide you ...

kinda sounds like you might have leaky head gasket at that cylinder. Or if its more of a regular misfire could be either plug, wire, or coil.
it has new Coils and plugs, what is a leaky head gasket what would that do and how much to replace. would that cause the gagging white smoke that smells ...

I first had a problem with Cylinder #2 misfire and the exhaust was so bad with a white puff of smoke and it gauged you if you smelled it. The I had another Code saying a P300 random Misfire and its getting worse. What could cause this. I have it ready to go to the shop on Tuesday and Im worried what ...

$80 is a lot cheaper than buying a new MAF. It's also a pretty cheap bill for a bunch of expensive unnecessary diagnostic troubleshooting. If that really fixes it, just count yourself lucky and walk away with some new understanding of "best practice" troubleshooting on our 3800 engines.

Generally ...

This topic has been resolved. It was the spark plugs all along?

Spark outside the cylinder is a good sign but not a perfect way of telling if it'll ignite the compressed air/fuel mixture in the cylinder.

6 plugs going bad at once is unlikely. May be they'll let it run well enough to throw a code. Seems likely they needed changed.

He said they checked the ...

Also, because this is easy to check, check your Fuel Pressure Regulator for a leaking diaphragm.
Pull the vacuum hose off the FPR (plug the hose with your thumb) and wait 3 to 5 minutes, looking for fuel coming out of the FPR tube that the vacuum tube normally connects to. If any fuel comes out ...
