does any body know why something is wrong with the engine when you change spark plugs, spark wires to new one?

Question

I changed the spark plugs and spark wires to new ones on the Dodge Caravan 2001, 3.3 litre engine.
When I started the engine the light on the dash board showed “engine trouble”
On the road the engine is not stable, especially with low RPM. When
I tried to accelerate and when I did, there was a sound in the engine area like a light low-sound explosion and it looked like the engine did not have enough power.
After the trip the dash board engine problem sign started to blink. I also checked the position wire on the sparks and it was in its correct position.
Does anybody know what the problem is and why it happened?

Thank you in advance for you answers.

Answer 1

If this problem only occured after you did this work then YES you need to back track and look at the plugs or crossed plug wires. Good Luck Sir

Answer 2

Changing spark plug wires are very funny thing meaning that you must be very correct about your application of the new hardware.Did you put the wires on backwards?, are your spark plugs gaped correctly,are they the rightrio spark plugs if this is not the problem, check the distributor cap's interior for cracks,burns,or broken electrode that extends to the rotor.Some times you mistakingnly broke the extentioner to the rotor therefore causing your problem.Also,even if the plug wires are new, they can be defective from the factory or the wires are packed too close to each other thus causing them to arc.open your hood at night without any light,start the vehicle and see if you see anysparks on any of the spark plug wires,if you do, you have a very bad wire, please change the wire.Is your distributor cap water tight?

Assuming the car was running decent prior to changing plugs and wires, it's logical that the problem lies somewhere in the process or possibly hardware involved with the spark plugs and wires. Giving the new plugs and wires the benefit of doubt, you may have accidentally plugged a wire onto the wrong plug. First check that each wire from the distributor is connected to the correct spark plug. Your owners manual may have a diagram to help with this task or you may have to visit the library and check out a shop manual.

If you determined that the wires are correct you may have a faulty wire or plug. If you are able to read the engine computer codes, it will point to the cylinder# with the problem. I've experienced this with my old Volvo. If you find the cylinder# but not sure if it's the plug or wire, try putting your old wire back in. If that fixes the problem, take the wire back to the store and have them give you a new wire. The same goes for the plug.

Answer 4

You got two spark plug wires backward.

With the engine running, unplug one spark plug wire from the distributor cap.
If the engine stumbles more or dies, plug it back in and try the next one.
As soon as you unplug one and nothing changes, that one is plugged into the wrong place.

There should be one more that is miss placed. When you find it , swap places in the distributor cap with the other "bad"one.

Answer 5

Sounds like you might of crossed a wire or two and put them to the wrong spark plug

Answer 6

Misfired,either wires were misplaced or spark plug's gap incorrect?Or the porcelain of the plug is cracked due to hard accessed of the inside bank when replacing.First,scan the PCM to see which cylinder is misfired ,or if you do not have scanner,take a closer look at the cables and plugs of the innner bank.Hope this helps.

Answer 7

you need to clear the coad in the computer or it may get worse seriously you can clear acoad by disconnecting the batt + and - for min and then reconnect them should turn the light off but not fix the problem must take it in too the dealer to run a scan on the computer and it will cost $$ depending on what is wrong hope that helped

Answer 8

Hi,yeah you coulda crossed a couple wires but it may be as simple as you didn't put them on all the way go back and check them push them all the way down with a little twsting motion til you feel them "click" in place

Answer 9

Double check the firing order. Sounds like you got one or more wires in the wrong place.
