You just need to go through a simple Idle Relearn Process.

The Idle Speed Control motor will cause the accelerator pedal to tap and the car will surge back and forth, actually acting like there is a lack of power during intial startup.


Whenever a battery is changed, went dead or the ECM computer is replaced.

In order to make the engine run normal again, you need to take the car through a relearn process. Otherwise the idle could be very slow or have a 30mph idle.

To enable it to relearn, here's what to do.

1) Disconnect the battery cable for 15 minutes, before hooking it back up.

2) (KOEO) Turn the Key On with Engine Off, just so the electronics are on, but without starting the engine and turn the climate control panel to off.

3) Push the off and warmer buttons on the climate control panel at the same time and hold for up to 5 seconds for the computer to go into diagnostics.

On the fuel panel screen it will display 888 then E52 and then 70.

When it gets to 7.0 shut off the key for 1 minute.

4) Repeat step 3, two more times.

5) Start the engine without pushing on the accelerator pedal and let it run for 18 minutes with the climate control panel off.

6) After 18 minutes put your foot on the brake and shift into drive and wait 1 minute.

7) Then turn on the a/c by pushing the auto button. It needs to be warmer than 60 degrees F so the compressor can engage. Wait 1 more minute.

8) Put the shifter back in park and turn the key off.

9) Wait 1 minute

10) Idle relearn is now complete and the engine should start and run correctly.

Cylinder # 3 has a misfire...#1) Defective coil on plug or the spark plug itself...#2) Contaminated fuel injector...See drawings below...The coil pack is the smaller of the two and sits to the rear of engine it is the most probable cause...Although the spark plug or the ignition wire (connection between plug and coil pack) could be at fault...so, before you invest in a new coil pack...Remove from both ends the wire from #3 and switch it with #2...if the fault code changes to p0302 that wire is bad...next Install a new set of plugs....Fault still present? replace the coil pack.....Unless recently changed new plugs and wires are a plus even if fault remains...saailer

My 01 taurus has very little acceleration for the first 2 and half miles each morning. After it warms up it has full power. Also when driving the car lerches, but not consistiently. Engine code say


You may have bad intake manifold gaskets causing the car to suck air until the car warms up and the gaskets expand. For had a problem with these in the early 2000\'s

Replaced plugs wires and coil pack keeps codeing cylinder 1 2 and 3 misfire


P0301 Code - Cylinder #1 Misfire
A P0301 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #1.

Symptoms may include:
- the engine may be harder to start
- the engine may stumble / stumble, and/or hesitate, other symptoms may also be present.

A code P0301 may mean that one or more of the following has happened:
- Faulty spark plug or wire
- Faulty coil (pack)
- Faulty oxygen sensor(s)
- Faulty fuel injector
- Burned exhaust valve
- Faulty catalytic converter(s)
- Running out of fuel
- Poor compression
- Defective computer

* This conditions is the same when code is P0302 or P0303.

Possible Solutions:
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

How do you change spark plugs in a 2004 hyundia sonata


It depends on which engine is in the vehicle. The 2004 Sonata came with two possible powertrains -- the 2.4 Lit L4, and the 2.7 Lit V6.

On the 4 cylinder engine, there are two coil packs and two ignition wires, Below each coil pack is a spark plug (#2 and #4 cylinders). The wire from # 2 coil pack goes to #3 spark plug, and the wire from #4 coil pack goes to #1 spark plug.

Now the 2.7 Lit V6 requires you remove the surge tank (intake manifold) in order to access the spark plugs & wires on Bank 1 (Right Hand side of the engine).

2004 F150 5.4L engine misfire


The concern is likely caused by the coil which sits on top of the spark plug. Your P0301 indicated misfire on cylinder 1. Your P0316 indicated it occurs on the first 1000 revolutions. Your P0171 indicated lean on bank one. Bank one includes cylinders 1,2,3 and 4. Your lean code is strange but could be related to misfire. I would recommend swap the coil on number one with number two. Clear the code and drive it. I would expect to see a P0302 which indicates the misfire traveled with bad coil. good luck.

Bad missing in motor on 2001vw beetle


If it is a 1.8 turbo the plugs are under the coil packs on top of the engine. A regular spark plug wrench will fit them. They are down in the block about six inches. They are easy to change. I changed them in about 30 min. The coil packs are held on by 2 torx screws.
