jkast Posted October 4, 2017 Share Posted October 4, 2017 Hey Guys looking for a little direction and were to go from here. I have done a lot of work to this car and need to get it through inspection. This 1999 legacy had a engine swap before I bought it and now has a 2.2. The previous owner did not have emissions so when I first got it I had to change the intake and get one with a EGR. This has all been done the car runs but has a miss on cylinder 3 & 4 and a EGR flow malfunction.Not sure were to go from here I put a timing light on spark plug wire 3 &4 and both are showing a erratic flash indicating a miss could the coil be getting a bad signal I swapped coils and the problem was still present. .

dp213 Posted October 5, 2017 Share Posted October 5, 2017 Did it run fine with the other intake on it before you changed it Quote Link to comment Share on other sites More sharing options...
jkast Posted October 5, 2017 Author Share Posted October 5, 2017 The car always seem to have a miss I don't think it was caused by the intake swap. Quote Link to comment Share on other sites More sharing options...

jkast Posted October 25, 2017 Author Share Posted October 25, 2017 Cylinder #1 145 Cylinder #2 145 Cylinder #3 150 Cylinder #4 135 These were done on a cold engine and removed only the plug from the cylinder that was being checked. The car seems to run without a miss at times. Missing is most present at low RPMs under load. Quote Link to comment Share on other sites More sharing options...
jkast Posted October 30, 2017 Author Share Posted October 30, 2017 Anyone else have any ideas on why this engine is missing ???? Are those compression numbers close to were a 2.2 should be? Quote Link to comment Share on other sites More sharing options...
