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

Thanks.

 

anyone??
