So I changed the spark plugs and wires to my car today with some ngk wires and iridium plugs and when I took it for a test drive at about 3k rpm the car started to shake weird and didnt have a lot of power but it still climbed rpm's. I thought I put a wire in the wrong plug but I checked everything and I even replaced the wires with the stock ones and it did the same thing. So I put back the old plugs too thinking if maybe that was it but it still did it??

So I dont know what it might be if everything was fine before I changed them. Im going to take it to a shop tomorrow so they can look at it but what do you guys think it is? Its still driveable but that weird shake and less power has me worried.

Its a 97 ek with an h22. It has an MSD 2 step if that helps.

Thanks.

 

make sure ur firing order is correct, and the distributor isnt 180 degress off

 

but just changing the plugs and wires affect the firing and distributor?

 

check the order the plug wires are in on the distributor because they might have got mixed up..

yes it can... u'll be suprise on how many people make this mistake.. i have a couple of times... sometimes u got the wires right but the distributor key (part that goes on the end of cam shaft) could be 180 degress off and cause it to mis fire like wut u are discribing how the whole car shakes... u could try turning it 180 degress b4 u mess wit the plug wires to see if that helps, but make sure ur firing order is correct first

 

what makes everyone think he took off the distributor to change the plugs and wires?


if you know plugs and wires are good and that they are connected well, whats left?.....

 

yeah i did not take off the distributor but i will try turning the dis key 180 degrees to see if thats it. thanks

check the gap in your plugs and try using your old plug wires see if the problem still happens. you did say this all happend after you changed the plugs and wires?
