Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

How to test an egr valve on a 94 topaz

Apply vacuum with a hand held vacuum pump, the engine will stall out or run really rough. If you have a very rough idle wet your fingertips and touch the lower part of the valve , if it is leaking then you will hear a sizzle and the valve will be very hot, replace the valve..

Where is the plug i plug codereader into on my 94 Mercury Topaz

I don't know the answer.

There was no prescribed universal location for obd 1 diagnostic connectors and it could be almost anywhere.

I suggest you speak to someone who is familiar with the model or try a dedicated forum for your model.

CV joints are getting bad in my 94 topaz. Bought whole other 94 topaz with bad engine for parts. It has almost new axel shafts cmplete that were put in. I want to remove them from junk car and install in...

the very best thing to do is get an auto manual for your car,they cost about $20.00 at auto zone or advance auto parts,even nappa auto parts should have what you need. fortunately for you ai that the 94 topaz is not really that hard to doe the transmission replacement on. the book will have step by step instructions and tips to save you questions and time.both front wheels have to come off,the cars going to have to be up enough off the ground so the transmission will clear to come out from underneath the car.if you're only replacing both axles,there's no need to remove the transmission.i want to be clear with you on that issue.front wheel drives are'nt that complicated to work on,it's just that your used to rear wheel drives right?take my advice please just buy the book and you'll see the section on axle replacement,follow those directions and you wont have only question is this,are the transmissions on both cars the same? if so then it's a go! thank you for choosing and wish you the very best of luck!
