88\' blazer problem\'s
I got the new 4.3 in and running and isn't too bad but not a vortec either. I'm haveing and problem with the gauges. The oil pressure jump's around at idle but is just fing at speed and my volt gauge say's it's only chargeing about 10 volt's although my headlight's are blinding. I also have a problem with the service engine light alway's being on. I first took it to a shop and they said it was the oxygen sensor. So I put in a new one and it keep's coming on. I have one of those code readers and after leaveing the battery undone overnight I went out and drove it. The light came back on and the tester say's that it's still the sensor???? Also, what's my best bang for my buck in performance? I put better ex. on it and want to stay with the manifold's. This thing already has a nasty shift kit and 3:73's. A spacer and chip??? Or is there something else I could do?
