Today my friend replaced a front spark plug for me and its easiest to reach if you jack up the front of the car and reach in above the tire. I watched as he jacked up my van and he put the jack under the big round metal center piece connecting the two front tires. Instead of it being centered on the round metal part it was more towards the drivers side and it was easy to see one side was up higher than the other. After the new plug was in I took it for a test drive. During the drive I noticed that I had to hold my steering wheel towards the right otherwise my van wanted to head into oncoming traffic. I tried a few different streets and ruled out it being the road. Before when I had my plugs replaced my van drove amazingly smooth. Today after replacing one plug(this plug fowls out every eleven months or so and the rest are fine, I understand why) My van vibrates now, the side mirror vibrates, my van actually runs worse than when we started. Although plugs come pregapped he still tried to gap it to the specified amount. Could the vibration be from the wrong gap? Plug not in correctly? Plug wire not on fully? Please help, I had him help me to make sure I made it out of town and back home safely. Now I am concerned to drive it. I usually do the plugs myself but the front takes an hour to reach without a jack. I can't see in there but need to know if I should go back and do it myself. Also, my van needs to be aligned but is only noticable when on the freeway it shakes slightly. Now I have to overcorrect it, just a hour earlier it went straight without any effort. Thank you so very much for taking the time to read this, I am worried.
have the same problem?
