Having problems with your 1999 Suzuki Esteem ?

Engine Missing I have recently changed my plugs and wires because my engine was mis-firing. I gave it a few weeks and it began to do it again, so I had both coil packs replaced. It ran great for another few weeks and now it is mis-firing again! What could be causing this?

Answers :

If you haven't checked your alternator yet, it would be good to do so. If the voltage regulator has failed, you may be running at up to 17 volts for a system voltage and this would fry more than only the ignition system over time.\015\012If you don't have a cheap Chinese multimeter and are in the US, you can buy one of these for under $20 any day of the week and Harbor Freight has them on special for $2.49:\015\012

\015\012Measuring across the battery terminals you should never have more than 14.5 volts (typically from 13.0 to 14.3VDC) with the engine running.\015\012Engine off with a normal healthy system you will measure 12.6VDC
