Q: car dies on me. chockes out on 1994 Nissan Pathfinder

I replaced the starter, and put a new ground to battery, and it started. and ran. Then I tuned it up. now when it runs for awhile it chocks out. when I hit the gas it quits. Not in the begining but when it warms up a bit. Put in a new fuel filter. Still. could it be injectors,pump?? coil?? Don't like getting stuck at lights. thankyou

When your Nissan dies out, you need to determine whether it is losing spark or fuel. So let it run in your drive way, and when it dies, start by spraying some carb cleaner ( NOT starting fluid!! ) in to a vacuum line that goes in the manifold and see if it fires. This is a quick way to check for fuel. If it does not fire then it is probably losing spark. ( process of elimination ) If it is spark, recheck all of your tune-up work. Are any wires loose etc. Is the coil wire on OK. If your car was running OK before you tuned it up, then you may have left something loose. This is a better way than guessing and throwing all sorts of parts at your Nissan, and potentially wasting a lot of money. Remember, there are many more parts to put on, than you have money!!!
