Question about 1991 Plymouth Laser

1 Answer

Laser Kh 1.8 91 - high idle, missing under load under 2500rpm

My car is a ford laser kh 1.8 1991, 5 speed manual.
It started off idling high once warmed up, but would then drop back after a few moments/minutes. Now, its constant once warmed up.
It 'seems' that once warmed up it also almost stalls due to missing, if say, i'm tryign to take off (under 2500rpm), but runs normally once its up past this rpm.
I took it to the garage and had new fuel filter, new spark plugs and a 'rocker cover seal' (for an oil leak) put in.... however this did not help, and they suggested an auto electrician.
There is also one unattached wire that is red and black, comming from the fuse box bit, to the right of the engine, near where the cable goes to the distributor cap. could be anything eh? can't see where it could have gone though.
Finally, the car, once heated up, if left for a minute or two, will not start. 3 goes later, it feels like its running on 2 pistons, and blows a LOT of smoke - reving it high helps to make an embarressing get-away.
Any help is appreciated, truly.

Trying to set the ignition timing on a 1991 KH Laser 1.8 SOHC Engine. The manual says to short Diagnostic Connector TEN with GND then set timing to 5 degrees. Does that sound right.


Try just moving the distributor to obtain an idle speed of 900 rpms. just don't over advance the timing or kick back at the starter and pre ignition knock will occur . don't jump any diagnostic wire .

OK, so is it still setting the codes? Or has that gone away with the transmission harness repair? The idle is controlled by the Idle Air Control (IAC) solenoid. Ford has had a lot of trouble with these. However, the symptom is usually low idle speeds that cause the engine to stall. I think I would be looking for vacuum leaks. Ford 4.6L engines are notorious for the PCV hoses leaking at the elbow where it connects to the back of the throttle body.

I have a 1992 Honda prelude that when it starts up it idles at 1100rpms fine but after it runs for like five minutes it drops idle to 900rpms and as soon as I hit the gas it stalls out..... It starts right...


on a cold start car will idle fast till it warms up then will drop to about 1000 rpm, try increacing idle speed so when it warms and drops it should stay idleing

When let off gas idle drops down and stalls. Ok at first when cold idle on but once warm stalls when let off gas. Problem started after removed battery terminals to clean with baking soda.


Not too sure about Toyota's but sounds like the computer has "forgotten how to idle". Fords do this when the battery is disconnected, as did some Cadillac's. Ford's solution is to let it idle for 15 minutes to "re-learn" operational characteristics of the engine. Found the following elsewhere:
Disconnecting the battery (for longer than a few moments) causes the onboard Engine Control Computer to reset and forget all the calibration data for your car. (In much the same way that you might have to re-program your favorite radio station push-buttons again.)

When you re-connect the battery and re-start the car, it has to "re-learn" all the correct settings for your particular car's engine all over again and the only way that happens is by actually using the car. Taking the car to the dealer as someone else suggested won't do any good, unless you like paying $65+ per hour for the mechanic to drive your car around and get it all warmed up. :-)

After about the first 10 miles, the idle will be much better. It will take 30-50 miles for the entire re-calibraton to finish. Take a 25 mile interstate road trip one way, turn around and come back home.
