well you are still having misfires. it could be from all sorts of thing. check that the coils are installed correctly . check that the ignition wires are connected properly. reset the eshaft profile (20 brake stomp reset) and check that the eshaft sensor is not dirty or damaged

Did you turn the key to the on position? After 20 stomps on the brake, your oil meter should move from left to right and left again real quick.

Anubis88 10-12-2011 02:04 PM

When you try the brake pedal stomp, turn the key to the "on" position but do not start the car.
Tap the brake pedal pretty fast, no need to do it hard, just fast.
Watch the oil meter when you do this and you should see it sweep to the left and back to the right.
If it doesn't do it, then turn the car off, wait a few seconds and then do it again.

Once you do get the oil meter to sweep, then turn the car off for about 20 seconds and then try to start it as normal.

As stated, you are still having misfires. Make sure coils, wires, plugs are all in proper order and all connections are solid. Sometimes when you think you have a plug wire on good, you really don't. Be careful, but you should feel or here a faint click when they are on all the way.

Hey I'm having a similar problem... About 3 months ago I had a few codes (P0301, P0302 & a few other). I replaced coils, wires and plugs and fixed the problem.... Last week I replaced the radiator and the next day I notice the car starts with major loss of power so I rev it for a few seconds and goes to normal and drives normal. Scanner is reading a P0301 again. Car starts normal when engine is warm. What could be causing this?

My guess is that you missed something when changing the radiator, or you knocked a plug wire loose? P0301 is a misfire as you probably know already.
Start by reviewing connections to plugs and coils.

Mazurfer 10-18-2011 08:30 AM

Anibus88 - so let me get this right.

You had a P0301 code changed the coils and now it's a P0302 code?
Is that right?
Did you change out all four coils?
When you changed the coils, did you also do the spark plugs at the same time?

Once we confirm these answers, then we(I) can tell you the next step to take.

and checking the trigger wheel and eshaft position sensor. you could easily knock the sensor about or at least dirty it up when mucking about with the radiator.

Mazurfer I do your procedure and there is no problem :) check engine is not blinking But I don't know why before reseting comp. check engine was blinking . I have change 4 spark plugs and coils. So from my point everything was ok but when I start car and run on the street I see a blinking check.

Problem was only from 1500 to 4000 prm I don't know why.

Anubis88 10-23-2011 05:03 AM

thank very much for everything:)

Mazurfer 11-01-2011 07:45 PM

Does this mean you issue(s) is solved and I can ignore the latest PM's or do you still need the info?

emerodi8 11-02-2011 07:40 AM

Is there a way to check the coils, wires or plugs to see which one might be causing the problem.

bse50 11-02-2011 07:42 AM

Timing light\oscilloscope for the coils.
Mileage and visual inspection work wonders for the plugs.
The wires shouldn't wear too much if the ignition system is in good conditions so it's best to replace them when the coils start failing.
