Q&A

I have a 99 Sonata GLS, 2.0 6 cyl. I took it to the shop with what I thought was a transmission slipping issue. After several hours of their tech checking every tuneup item (compression, timing, etc.) they said that the front 3 cyl were not firing and that it must be the ECM chip.
I took it to the dealership and they said it's never the ECM but usually a tuneup item. They ran the same checks and 2 days later said it was the ECM. They finally get the right one in and it did not fix the problem. They are at a loss now and consulting with "Hyundai Specialists" which I assume means the manufacturer. I believe he said that the injectors are working on the front now, just not firing.
Anyone seen this?
