Guys,

 

I bought a '96 OBW (2.5L) auto tranny with 188K mile on it. The block had a crack in it so I got a short block from a '97 and installed my heads, etc. I replaced the timing belt and all the hoses, filters, seals, plugs, etc. when I did the job. The car is getting about 18-19 MPG in mostly city driving and about 22 on the highway. Most people seem to be getting more MPGs. It also seems to run sort of unevenly (pulling harder and then softer at constant throttle settings) but otherwise runs perfectly. Starts right up, no smoke, some piston slap (I think) but it's running very reliably. I never made ANY adjustments of any type when I reassembled the engine. I'm just wondering if ignition timing is adjustable and if this might account for my poor mileage.

 

Thanks,

 

Todd

The ignition timing is controlled by the computer

If you you are off even by one tooth when installing the belt it, you will notice the difference.

 

I know I did.
