Possible faulty crank sensor or idle speed controller, fuel pump relay, or ignition module. Get a data scan and see what's sensor might out of range or defective. Check for clogged fuel filter also.

You need the sensors of those functions, which you don't have installed. I would go back to the correct part.

Well, for starters, your problem got posted under 1985 Oldsmobile 98 - then you said it was a 95 Oldsmobile 98 Regency Elite (HUGE difference between 85 and 95)...then it would be REALLY nice to know which engine we are talking about.

I'll just go with what you said last: 1995 Oldsmobile Regency Elite (Two engine possibilities)

If you have the 3.8L Supercharged engine (VIN CODE "1") it is on the left side of the engine near the oil filter.

If you have the non-supercharged 3.8L (VIN CODE "K") there are TWO of them. One is near the oil filter and the other one is in about the same location on the other side of the engine block.

Please also note that MOST fault codes for knock sensors are not caused by the knock sensors themselves. (they do fail, but it is very rare.) Usually there is either a wiring problem to the knock sensor, or the engine has internal problems causing a "knocking" or "ticking" noise which causes the engine computer to "think" that there is a problem with pre-detonation causing an "ignition ping". The code sets when the computer has retarded the ignition timing as far as it can and the "knock" or "ping" does not go away....usually it doesn't go away because it is not caused by ignition timing. The knock sensor is just doing its job and reporting the knock. It does not know the difference between a knock caused by ignition and a knock caused by internal engine problems.

Yes this is normal

through the trunk.

Check fuel pressure,spark.If no spark possible crank sensor or ignition module.If no fuel pressure tap the bottom of the fuel tank with a mallet while someone is cranking the vehicle if it starts then you will need a fuel pump.Also if you have spark and fuel but the engine feels like it bucking while turning over,take a hair dryer and heat the coils up.you may have a bad coil pack.After they get warmed it night then start as the coil resistance changes.

Have you replaced the oil pressure sending unit?

Oil could be full, but does it give the correct amount of oil pressure? Check the oil pressure with a by-pass gauge on the engine. That will answer all.

There are 2 problems for code 34. First, is manifold absolute pressure(MAP) sensor signal voltage low. Second, Mass Air Flow (MAF)sensor signal-low airflow indicated.I dont have anything for the MAC.Hope this helps
