I would suggest Installing a New K&N Air Filter and Get 2 Cans of B12 Chemtool and run 1 at a Time througha Full tank of Fuel. The filter will Increase the Air flow by 50% and the B12 will Clean the Entire Fuel System. I use these Both in My 95' Silverado when it does this and always works!

    You might try a Flush and fill on the Tranny and Check the Rear end.

WHAT ARE THE SPECS FOR FUEL PRESSURE, HOW MANY P.S.I SHOULD I HAVE IN FUEL LINE? 89 NISSAN P/U 2.4L


Generally speaking, modern gas fuel injected systems average 30-40+ psi. Older carburator engines only required 3-7 psi. High pressure in the injector helps atomize the fuel for better air-fuel mix. Check maufacturers specs and use proper tools to measure fuel pressure. Eye protection recommended.

What would cause the van to start spitting sputtering misfire when going up hill or encline


Could be clogged fuel injectors. I had a problem similar to this. Car ran okay on flat areas but would spit and sputter going up inclines. I took mine to an oil change place and they ran a cleaner through the system. This fixed the problem and I put an injector cleaner in with every 3rd tank of gas to keep this from happening again.

My 2011 mustang has 55 thousand miles on it and 10 grand in upgrades from a great mech shop iam out of town and drove thru some water on the road now it spits and sputters at high rpms and will stall


you may have poor ignition wires that need to be replaced or a bad electrical connection that is affected by water either for the ignition system or the fuel injection system. just some places to look.

Sputtered died


A 22r engine uses a carburetor, and a 22rec is fuel injected. If you have the fuel injected model, the throttle position sensor could be faulty.

When u push on the gas it spits and sputters, it ran out of gas like 2 weeks ago and yes sometimes i do let it run low on gas. It spits and sputters when i turn a corner or go up a hill


Could be a clogged fuel filter, and or dirty fuel injectors. Try running some strong injector cleaner through it. It may take 2 or 3 times before it cleans the injectors out fully.

Car spits and sputters and stalls after driving a while


sounds like a fuel pump problem,with fuel pumps u can have pressure but not enough volume,try goin up a steeper hill in 2nd gear and get about 3000 rpms on the engine and see if it really drops out bad and is really gutless,if that happens without a check engine light coming on it might be yur pump and u should also replace the fuel filter at the same time,hope this helps
