3.8 motor has been running great till one day I started it up and blue smoke puffed from the tailpipe. Then, after acceleration from a stop the engine would ping like it was out of time or bad fuel. It also would puff some more smoke at the very point. I self diagnosed as a timing chain stretch so I replaced the timing componets, (including the tensioner) and the camshaft synchronizer. After of which there was no change in perfomance. Still pinging and smoking on acceleration. Also at idle if you open the throttle up gradually, engine hits what I would call a rev limiter. Getting frustrated with this issue because the engine ran good up to that first day. Any help would be appreciated. Thanks, Larry
