The power steering system may have a leaking return hose from the steering rack and pinion to the return reservoir. This leak can cause the power steering pump to suck in air into the steering system and cause noise and...

Hello, It sounds like you may have a failing wheel bearing on the driver side of the vehicle. It is not uncommon for one side to fail prior to the other side. A wheel bearing will usually fail due to...

Your issue doesn’t appear to be a starter problem. The starter’s only job is to crank the engine. And from your description it is doing that (unless it is cranking very slow). Your problem seems to be that the engine...

Rough idle is typically fuel and/or ignition system related assuming that there are no mechanical problems with an engine such as uneven or low cylinder compression. The problem is diagnosed, in part, using a real time scanner which reports a...

Any improperly sealed or mounted airbox may affect the reading of the mass air flow sensor resulting in the shaking or rough idle you are describing. I would suggest properly securing the airbox and see if that does not fix...

You replaced the accelerator pedal and the throttle body itself. The throttle position sensor (TPS) is a sensor that is located on the throttle body used to monitor the throttle position of the throttle plate inside the throttle body in...

Hi there. Check the camshaft position sensor and see if its plugged in. If the sensor is plugged in and the engine will crank, then the camshaft could be out of timing and needs to be reset. If the engine...

If the front drive shaft is spinning and not able to be engaged, then the chain in the transfer case could be broken. For the transmission to be in neutral in all the gears, but lock up in the park...

Hello. It sounds like your transmission either did not get completely full of fluid after the service or it is leaking fluid again. To check the transmission fluid, start the car and leave it in park. Next pull out...

Hi Clifford. Thanks for contacting us today. Based on your description, it sounds as if you've got a few air bubbles trapped in the brake lines. This is rather common with brake conversion projects, as it can take quite some...

A rough idle indicates that your engine is misfiring. There are many reasons why a car would misfire. It could be a bad ignition coil or spark plug. It could also be a bad control module or wiring issue. If...

The air fuel ratio is off on your hot starts probably due to sensors or controls operating out of range or perhaps due to a stuck open EGR valve. Heat affects ignition coils and can also adversely affect sensors such...

If the engine cranks at adequate RPM, be sure there is adequate fuel in the fuel tank and that the fuel is not old. Download any OBD-II trouble codes that have been stored and examine those codes for diagnostic clues....

Hi Kyle. Thanks for contacting us today. I'm not sure whether or not the alternator replacement has anything to do with this symptom. However, it is possible that during the removal, an electrical fault may have disabled a transmission speed...

Hello - quite likely, the inconsistency with your gauge operation and the occasional dead battery are related, with a short in the wiring perhaps. This problem can be diagnosed by connecting an ammeter to the positive (red) battery cable, observe...

Describing the symptoms is very important when your car is not running like it normally does. Only you know what the car usually acts like. If the vehicle is: not starting, blowing fuses, having battery trouble, showing flickering lights, etc.,...

I would recommend having all of the vaccum lines checked first since those are a much less expensive repair than carburator issues. If any vaccum lines are old, brittle, cracked, or broken, I would recommend having them replaced. If this...

Intermittent low fuel pressure could cause the problem you are describing, perhaps aggravated by a restricted fuel filter, however, stalling is also commonly due to faults in the ignition switch, hall effect sensors, idle speed control (ISC) system, loss of...

The idle air control valve is common for causing a rough idle in many cars, but it sounds like you have already corrected that. Another thing you may also want to check is the crankshaft position sensor. A crankshaft position...

This is a fuel supply problem. Fuel pressure will be the key indicator for which component of the fuel system isn't performing as needed. Check to be sure the fuel pump relay is good, and the fuel pump is running...

You certainly don't see many Pontiac Torrents around. The 3.4L is a common engine, however, and I know it well. Since it doesn't use a timing belt, I assume you must mean you replaced the serpentine belt. The only way...

Regarding the fuse, the high current probably welded the fuse to the fuse holder. YourMechanic can attempt to salvage the assembly by trying a fuse replacement without destroying the fuse terminal box. If you are lucky, putting a new fuse...

It is possible that you have an internal transmission issue. It is also possible that the clutch itself could be worn out causing this issue. I would recommend having a qualified professional inspect your transmission to determine the exact cause...
