1990 900 turbo leaking hydraulic fluid

QUESTION:

1990 900 turbo leaking hydraulic fluid. seems to be toward the radiator end of the engine. replaced clutch master cylinder, that was not the problem. any suggestions? 

ANSWER:

Only 1 thing on your car uses hydraulic fluid. That is the transmission, the brakes and clutch use brake fluid (highly corrosive nothing like hyd fluid). If the master cylinder is running low, you are losing brake fluid. Probably the ABS pump or control unit. I believe that is where they mount it. More likely though is a transmission leak from the cooler lines (they run into the radiator). Check both of these.

2000 4×4 Isuzu Trooper 3.8 Liter. When it starts up it idles fine

QUESTION:

I own a 2000 4×4 Isuzu Trooper 3.8 Liter. When it starts up it idles fine, however, when you put it in gear the RPM goes up and you have to keep your foot on the brake pedal because it feels like it wants to go and move fast. Very unusual to experience. Not sure if this is a sensor problem or not. The transmission was replaced or rebuilt in April 2007 with 120,000 miles. Any idea?

ANSWER:

I looked up technical bulletins on your vehicle and it appears there have been problems with the Accelerator Position Sensor. Beyond that it will require some diagnostics by a good technician to determine the exact cause.

Key won’t come out of ignition

Question:

2000 grand am. Key won’t come out of ignition. can remove it by pushing button on underside of steering column. Electrical release solenoid beside Ignition  switch is working fine, where is the signal coming from that activates the release? 

Answer:

There are 2 bulletins. One is for making sure the shifter is totally engaged in the park position. If it hangs up and doesn’t go into park, it won’t allow the key to be removed. The other is for a key cylinder that will not rotate back to allow the key removal. This involves drilling a hole in the aluminum housing to drill out the pin that releases the cylinder.

started smelling a burnt plastic smell then the brake light started coming on

Question:

I have a 2002 Hyundai Sonata GL and started smelling a burnt plastic smell then the brake light started coming on and going off, and my dashlights started dimming then lost power all together. Diagnostics were run and were told that my battery was good and that all cylinders were running and that everything looked fine, we cannot figure out what is going on – there is no fluid drippings. Already Tried: Diagnostics on battery, checked under hood, checked battery cables, checked fluids, checked to make sure wasn’t a bag on the muffler, can’t find the starter to see if the cables to the starter were okay though

Answer:

Check the engine drive belt tensioner. It may be sticking and allowing the belt to slip intermittently, this would cause you to lose charge and smell burning.
