You more then likely have an injector that is over fueling or leaking fuel. I would use a temp gun on the manifold and the one that is hotter then the rest is the one I would change.

Code po430 comes up twice on scanner little skip and gas milage getting worse


Most likely a failed exhaust converter, that should have lasted
12 to 14 years

Google your codes

So that motor has had issues for years, I would guess

Cylinder Misfires,Rich Fuel Trim ,neglect or something

Have to fix all it's problems, then replace the converters

Idel loping on 2001 toyota tacoma 2.7 liter


Could be possible a spark plug wire is grounding out and making the cylinder skip a fire. If you can do this yourself carefully, you can pull each plug boot loose and if each of the boots pulled off the plugs makes the motor seem to skip a little then, that would not be the problem, I have seen wires that makes a motor skip while it idles, but it does not happen every time it fires on that cylinder.

Some of the older model trucks even though they run on OBDII systems, they may not have a monitor for the plugs misfiring codes.

Careful of fans, loose clothing, and pulleys plz, if you do attempt this as a DIY attempt.

Hope it helps.

Starts but will not idle


Most Lesabre have the 3.8 engine. The engine has a device called an automatic idel speeed motor or AIS for short. It's held on with two torx 20 screws and a 4 wire electrical connector on the side of the Throttle body. BUT BEFORE YOU GO REPLACING THIS DEVICE THAT CAN COST OVER $50. Try this first. Don't drive the car around this way just test it! Remove the big vacume hose from the power brake booster and put your finger over the end of the hose going to the motor. Have an asstant start the car and hold the gas so it'll keep running, trying to go as slowly as they can. Slowly remove your finger from the end of the hose and the motor should pick up speed. you should be able to get a good idle with your helper completly of the gas. if you do the idel motor is'nt working ( right) so your not done checking. Let's say you can't even get a fast idel that stays. The timing chain needs checked and other vacume or engine control codes need checked. Has the check engine light been on? ( with the engine running) . If it has the idel motor will set a code as will a cam senser and all the other sensers on the car. Follow code charts if a code is found. Most auto parts stores will check your car for free for codes but their recomendations very with the experience for the operator of the tool, and if they were good enough to make the mechanics money why are they in a parts store? If you can acheive a good idel playing around with the vacume hose then put it back on and go to the next step. Remove the Idel motor and clean it and the hole it came out of with oven cleaner. Just like cleaning an oven don't get it on you or the wiring part of the motor. With an OHM meter the pins will show two different pins hooked together ( two Pair) If you get only one it's bad. Every pin is connected to just one other pin. If not it's bad. You can get new cheap ones that are bad. I use cheap ones and cross my fingers. If they work the first time their good for a long time. Then you have to learn the idel. Try to learn the idel with the old one cleaned first. Start theengine and hold the idel with the gas pedel. after holding the speed at 2000 Rpm for two minutes ( a good engine will do this easy) let off slowly it should idel down slowly then (catch) and speed back up on it's own. If it does your fixed and go on your merry way.

Rough idle then stalls


Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.

Engine skips


When you press the clutch the engine control computer senses the clutch is in and adjusts the idle speed, maybe the idle speed control motor is dirty and sticks, this will almost feel like a skip or miss, do you have any trouble codes?
