2.3L Engine Miss...
I was driving my trusty steed home last night, 1990 Chevy Beretta, with the 2.3L HO. This car has just under 200k. It was purring perfectly, until I pulled up to a stop, and when I went to accelerate the motor sputtered a bit and lacked power, suddenly there was a pop of sorts and it took off at normal. The next stop it did the same thing only this time it never came back. The car has a horrible miss now. Any one have a similar problem or know what might have caused this?
Thanks Tex |

Re: 2.3L Engine Miss...
I am responding to my own thread so the next guy can see my solution. My car was clearly down a cylinder, not 2 cylinders as is common. The first thing I did was run a compression check to make sure it was not terminal. The compression proved to be just fine. Next I tried to determine if it was fuel or electric. Because of the ease, I tested for spark first. This is where I found that the #1 cylinder was not firing. The coil housing is a common problem, so I tested this for continuity. It showed it was working fine. We changed the position of the coils. Almost everyone out there is saying that a bad coil pack will cause 2 cylinders to misfire. I am here to tell you that is not the case. After changing the coil packs the misfire moved to the #3 cylinder. Replaced a coil pack for 36 bucks and she purrs like a kitten once again. Very inportant to note that there is misinfromation being spread abroad about the coil packs not causing just 1 cylinder to misfire. If you dont believe me send me $20 bucks I have a coil pack I will send you to install on your car. lol....
