VAN emits whitish bluish smoke and bad fuel smell from exhaust

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


Smoke from exhaust and bad fuel smell is very much noticed on many car/truck models.


That type or smoke indicates the van is getting to much fuel. you may want to check the engine vacuum and compare it to what the map sensor is reading . low vacuum reading will make the ECM to add fuel to the engine because it thinks the van is accelerating.if the map sensor and the engine vacuum are reading the same check for a vacuum leak especially around the lower intake manifold.

Getting this basic details inspected checked will help,to confirm the exact problem.

Thanks.
