Hi there. If you have coolant in your lower manifold also then at the very minimum you need to blow it out with compressed air. I would recommend removing the lower manifold also to make sure that you get it...
From what you've described you'll need to have the codes retrieved from the computer and have them diagnosed. This sounds like you are getting misfires and should start with checking the ignition. Also, check the spark plugs for signs of...
It will not hurt your motor if you use regular oil after using synthetic oil. Just make sure to drain as much out as possible, and change your oil filter. There is no difference in motor design. Some manufacturers prefer...

The engine may be leaking oil onto the undercarriage where you can't see it, but more likely, the engine is burning oil. This generally happens when either the valve guides or piston rings are worn. If there is too much...
Hi there. Since your issue is intermittent this would lead me to believe you are experiencing a bad connection behind your dashboard. A loose connection between your light bulbs and sockets will cause this problem along with a fault in...
If the engine had seized because of low oil, you would have heard some excessive engine noise and probably had some overheating as well. In the absence of those signs, your problem may even be something minor. But knowing that...
Check to be sure that the transmission fluid level is correct, especially that the level is not too high or low. Also, check the condition of the fluid. Apart from that, the list of "typical" causes of P0741 includes: Faulty...
Hello, The first thing to check is all the fuses to make sure they are seated. There will be be more information needed to understand why the truck is not restarting. If it cranks and won't start, a scanner will...
Hi there. There are several possible causes for the lightening bolt to remain on. The PCM (powertrain control module) has recognized an electrical fault in the ETC (electronic throttle control) system and disables the starter relay, creating a no crank...
This can be caused by a number of things such as low coolant levels, a faulty thermostat, or a failing coolant fan switch. As you may know the coolant fan switch helps to maintain the proper coolant temperature by turning...
Hello, I would advise you to first check and see if you have a blown fuse for the power door locks. If the fuse is good then you will need the aid of a mechanic who can removed the door...
Hi. There may be a couple of reasons why this could be happening. There could be an intermittent problem with the starter not engaging when it should be. This is usually caused by a problem inside the starter solenoid. ...
The reason the shops told you to replace the engine is that they do not overhaul engines. They can only replace it for you with a remanufactured or used engine. An overhaul is a third option but would most likely...
Hi Seantez. Thanks for contacting us tonight. In most cases, when you shift into reverse and the vehicle stalls, it's due to damage within the valve body of the transmission. If your Cutlass Supreme is fuel injected, clogged injectors or...
This circumstance is not unusual and can be caused by the use of non-OEM rotors and brake pads and also the failure to re-apply factory specified shims and/or appropriate anti-squeal compounds and lubricants. Unfortunately, if and once non-OEM parts and...
Hello - first thing to check is what problem code remains set. If still a TPS, double-checking the wiring at the throttle body, and also checking the throttle pedal actuator sensor. This is the "transmitter" whereas the throttle position sensor...
With intermittent no crank conditions, you most likely have a bad connection in the primary starting circuit. This is the battery, the positive and negative battery cables and the starter. Even though you have replaced the starter, new or remanufactured...
I've got a video that is called "fixing an overheating car." It shows every possible thing that can go wrong and it's only four minutes long so watch it and test that. You'll want to try the last test on...
Coolant leaks can be external or internal. If the coolant is leaking internally into the cylinders or crankcase, that will require a fairly significant repair. If the coolant is leaking externally, unless the leak is at the head gasket or...
Yes, you do have an old truck, but that doesn't mean it can't run well. If you noticed this problem about the time you replaced the catalyst, it could be that the replacement catalyst is not large enough to breathe...
