I need to know the drive cycle 4 the 98 lesabre

Unfortunately it is not a certain amount of time or miles that the car needs to be driven.

There are several 'readiness monitors' that basically cover each emissions related system. For instance there is an EVAP monitor that checks the EVAP system and all of it's components under certain specific conditions (No VSS, TPS, O2 sensor, IAT, MAP, Fuel trim, Injector ciruit, EGR pintle position, ECT, or MAF sensor DTC codes set; Start up engine temp 40F-86F; gas tank between 15% and 85% full, Barometer above 75 kPa, system voltage 8V-16V).

So more information is needed as to what failed you the first time. What DTC code was triggered?

If the problem has been fixed right, the history codes will go away after 40 CONSECUTIVE drive cycles WITHOUT the problem re-occurring.

Good Luck.

Take it to a professional.

Sometimes a few days, starting and running it a few times a day. It could take a week or more. It depends on how many driving cycles and miles. You should run it long enough each time for it to reach full operating temp.

Crank sensor. Next time it shuts off pour or spray some water on it then see if it will crank. If it does replace it.

My sincere apologies for the delayed response.
I am personally going back to answer your unanswered questions.
I have only been a free contributor to this site for the past 4-months.

I do not know if you still need this information, but I am going ahead and answering it anyway.

CLICK on the following LINK. It has the Belt Diagrams you will need.

Make sure there is enough transmission fluid in it chances are the fluid is low.

First you need to remove the egr and clen the carbon out the pintle gets clogged and restrics the flow and in turn throws a code as all the checks are made by the pcm"drive cycles".

You can disconnect the battery cables for a couple minutes which typically resets the ECM to some predetermined (default) settings which may make your vehicle run or respond slightly different than it currently does but as you drive the vehicle it will relearn and adjust as needed. If you prefer to wait awhile then it will turn off itself after several --several cycles of the ignition ;so long as the problem is fixed or no longer exists and there are no other problems.

Hello;
You need to have the linkage adjusted. Over time, the linkage can go out of adjustment. If this is a column shift car the mechanical linkage may have shifted from hitting a bump or such. Hope this helps, let me know if I may be of further assistance.

power steering is a cycling system all you need to do is fill it and run the car
