1990 Ford Bronco Q&A
1990 Ford Bronco Question: Backfirers
I have a 1990 Ford Bronco that after I drive it to town (20 miles there and 20 miles back) it starts to sputter, pop and back firer as I go up the mountain I live on. The clime is about 350 feet from the road up to my house and about 1000 feet from town to my house. I also have a very hard time starting it in cold weather. I have replaced the MAP sensor but it still does it can you help me with this problem? - kmpec
This is a good question but I don't gather much particular information from what you've written. I assume you replaced the MAP sensor for the problem you write about. You haven't given me any history of maintenance or repairs so I'll assume you haven't done any recently. I'd recommend is replacing the fuel filter if you haven't in recent memory. Also check the intake air ducting for loose clamps or defects that would allow air to leak into the intake. Check the sparkplugs for wear or cracks, check the sparkplug wires for condition, if they are too old the resistance could be excessive or the insulation could be faulty, causing ignition failure under load climbing your hill. One other possibility is that the airflow sensor (MAF) is failing, that's not uncommon for this vehicle. Any of these items could cause the hard starting. Maybe a complete tune up is in order with a diagnostic check to look for electronics problems. Get a Ford expert to handle it, you need someone with experience and knowledge of the problems associated with your model and year vehicle.
