Hi there. If the relay is clicking, then there is power to the glow plug controller. Remove one of the glow plugs and look at it. If the glow plug is white and has some blue on the rod, then...
Hello. It sounds like your problem lies in the fuel/air mixture going to the carburetor. If the fuel/air mixture is not accurate, the idle needs to be checked with a vacuum gauge and adjusted to the proper idle and vacuum...
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 may be a sign of a faulty MAP sensor as the vehicle responds adversely to a load put on the motor (i.e. putting it in gear, making turns (which makes use of the power steering pressure switch) turning on...
Hi there. Unfortunately this is not a service one of our mobile mechanics could offer, so we're not able to offer a quote or estimate. In regards to whether or not it can be done, the answer is "maybe". If...
Hello, and thank you for writing in. When diagnosing this type of no-start, there are several things you will want to test first to make sure the basic charging system is working to supply the starter with power. When driving,...
There is a parasitic load applied to your battery with the ignition is off. Keep the test light on the battery and turn on one thing at a time and watch the light. If the light goes out, then that...
Hello - backfiring (https://www.yourmechanic.com/question/car-backfiring-and-spitting) can be caused both by timing issues, as well as air leaks (unmetered air) into the intake. I would first have the timing set (https://www.yourmechanic.com/services/adjust-ignition-timing) to be sure it is correct - since there is some...
Hi there. If you check the engine oil and see the oil look like a milk shake, then the engine oil is mixed with coolant or water. Also if you are finding gasket material in the engine oil, then a...
Hi there. You can swap the engine from a 1981 model to a 1997 model, but you will have to swap the entire power plant, the engine, the transmission, and all of the electronics including the exhaust system through the...
Hello. There are a couple of things that come to mind. The wire that is not connected to anything could be the wire that is causing the problem. That wire could be shorting the turn signal system once it is...
When you operated the car right after the tune-up, the coil somehow "found" a good enough path to ground for the ignition to function, but it was probably a high resistance path. That would have increased the load on the...
If you can operate the engine to bring it to normal operating temperature, the ohm readings will be more accurate (the following readings are for a hot engine). For the pick up coil (magnetic pick up assembly), connect your ohmmeter...
Hi there. When the front end becomes bumpy while driving, it's typically caused by struts that are worn out, steering stabilizer bushings that are damaged or a different suspension component that is beginning to wear. In order to correctly diagnose...
TransGo makes a manual shift conversion kit for the 4L80-E (http://www.transgo.com/products.php?category_id=98&parent_id=31&product_id=203). This shift kit installs inside the valve body and turns the 4L80-E into a purely mechanical transmission so no computer at all is required. This kit will require vacuum...
The kickdown cable is too tight and needs to be back off. The kickdown cable controls the throttle valve on the transmission which overrides the transmission shifting. If the cable is too tight, then the transmission will not shift and...
The cable that needs adjusted is the kickdown cable for the transmission. This controls the throttle valve on the transmission which keeps line pressure higher than the shift pressure to prevent the transmission from stack shifting. If you need further...
Hi there. Remove the fuse to the reverse lighting system. On the side that does not have power, use a digit ohm meter and check for resistance. The meter should read OL (out of limits). Now, turn on the ignition...
Hi there. Unfortunately, due to the complexity of this type of work, and the importance of using a shop to complete this task, it's not a service our mobile mechanics offer. You should contact a local speed shop or engine...
As a general rule, car engines do not like cold weather and do not do operate as well in cold weather. When you start your car in the morning and turn the key to on, the coolant temperature sensor immediately...
