I never cease to be amazed at the number of people that refuse to buy a scan tool for their Buicks. Almost weekly, I get one or more emails from people that have a problem with their car and they start off with a list of everything they have replaced on the car and it still does not run properly.
When I ask for scan tool data, they tell me they cannot afford to pay $250 for a Scanmaster yet they have just listed a lot more than that on parts they have replaced for no reason other than they hoped it would help.
When I point out that a Scanmaster not only gives a snap shot of the sensor data but it also provides a full time monitor of timing retard so one can avoid potential damage to the car from detonation, they tell me they don't have a detonation problem. How do they know this? They don't hear it.
Next thing they tell you is that someone told them they may have a blown head gasket and they know that is b.s. because they never heard any detonation so the previous owner must have lied to them because it started acting funny three months after they bought the car and they never heard any detonation.
No scan tool, no fuel pressure gauge, no boost gauge, no nothing....tel
l me what to buy, but, I can't afford to buy a scan tool. $1500 worth of tires and wheels are no problem, but I can't afford a scan tool.
Check engine light is on, should I be concerned?
I know my car is running rich....becaus
e I smell it in the garage....no, I cannot afford a scan tool, but I replaced the coil, the module, the tps, and the o2 sensor. Got a check engine light? No, should I? Why did you replace all those parts....oh, sorry, you said it smelled rich....
These cars are 25 years old. Some have been well maintained. Others have been thru five or six owners who abused the heck out of them and knew absolutely nothing about taking care of them.
If you want to enjoy them, learn to take care of them. Start by buying a scan tool (don't buy one that is a generic model that does not monitor timing retard all the time-borrow those for troubleshootin
g but don't think you are safe without having full time timing retard data staring you in the face) A fuel pump, injector, etc can act up at any moment and when they do, bad things happen when you keep going full throttle.
Yeah, I know $250 is a lot of money...but it is cheap compared to a crank that has been ruined by detonation over a long period of time, a hammered piston pin, cracked pistons, blown head gaskets, and rods thru the side of the block.
Some people buy a big turbo, another converter, chip, injectors, etc but won't spend money on a scan tool...
