Hi there. It looks like you've replaced most of the usual suspects here, but it could be several other electrical or fuel related components that are causing your Cutlass Ciera to not fire-up including spark plug wires, spark plugs themselves,...
The popping sound from the engine sounds like the engine's timing is off or the fuel system is not delivering enough fuel to the engine. There could be a fuel injector that maybe sticking and not spraying properly. The popping...
Hello, It sounds like you may have a faulty oil pressure sensor. The oil pressure light will usually come on when a few things could be happening. Either the motor is in fact low on oil, the oil pump could...
Hello. The symptoms you describe can be caused by many things. If you are feeling a vibration when putting the vehicle into gear then it may be possible that there is a transmission or engine related issue. If the transmission...
Hello, thanks for writing in about your Oldsmobile Cutlass Ciera. If you are loosing fuel pressure after it gets hot then you most likely have a fuel pump that is locking up when it gets hot. The connector to the...
Yes, corrosion on a ground terminal or splice point can cause various engine and electrical systems issues. Looking at the wiring diagrams I see nothing related between the entertainment and engine control systems that jump out at me as the...
It will depend on the the fault that is stored causing the service engine soon light to be illuminated. Based on the description, I would suspect either an input sensor to the engine management system, such as an oxygen sensor,...
Hello. Unfortunately, without hearing the noise myself it is hard to make an accurate recommendation. The first thing that needs to be determined is the type of noise that is present and the possible sources. Rattling or knocking noises while...
There are many potential causes for your concern. Stalling often means the vehicle is getting too much air or not enough fuel. It can also indicate a problem with the ignition (the crankshaft position sensor is a common problem on...
Most older cars have oil leaks. Sealing technology has just not kept up with mechanical improvements to engines so much so that leaks often kill engines rather than mechanical problems. So, it is not unexpected at all to have an,...
Hi there - your car radio is equipped with a security code mechanism to deter radio theft - a bigger problem in 1994 than today. The Owners Manual should have the code (4 or 5 digit number) written in it...
Hi there. As you already know, replacing components without diagnoses can be expensive and time consuming without resolution. Assuming, the engine sputters upon quick acceleration could be, the spark plugs breaking down. It could be, a partially restricted exhaust, ie;...
There is a 20 amp courtesy fuse that is common to all of the electrical systems that you are experiencing problems with. The fuse is in the fuse block and is labeled "CTSY," and if it blows, then it can...
This sounds like it could be a serious issue and should be looked at. Several items could cause a noise such as this when braking. A failing lower ball joint is one such possibility the other could be worn or...
If you already replaced the sensor then now it will need that connector you've mentioned. Replacing it may fix the code P0502. The code P1406 is for the EGR valve position, you would need to have the valve tested to...
Hi. A test that can be administered would be if you have a spare key, try to turn on the car with that key. If it turns on, then that would indicate you have a bad key and you should...
