Hesitation at low speed-engine light on

Fuel filter first thing to check after having contaminated fuel removed. Clogged fuel injectors, crank or cam sensors.

mine did the same thing and it was oxygen sensor
since engine light came on there should be an error code
on computer.Get a diagnostic checker or take to a garage and have them hook uo to the diag connector. I bought a diagnostic checker few years ago and it has come in very handy
sure hope this helps!!

Hello I have a 1995 Sonoma 4.3 with 150.000 on her and she ran great tell last week went to pick up a lite trailer and dove it home no problem drove it all day after that. The parked it running fine and next morning it won't hold a idle but clears up at 3000 RPM runs fine drop in gear and it won't stay running??? Cleaned TBI and there was a new fuel pump and filter put on it less them 7.000 miles ago. Found vacuum leak on the booster to manifold fix that still runs like it is misfiring??? Any help would be great thanks no check engine light on.

does it seem to sputter or hesitate when you excellerate through a turn?

you need to put it on a scanner to what the code is ( that is why the ck engine light is on ) then if you give me the code we can go further

is the check engine light on? have you ever serviced the injectors? if not try that first because there are many things that give the symptoms you spoke of. but this is the cheapest.

Take van to reputable Ford dealer and have them hook it up to computer and check for any codes.
The vehicle computer might have to be reset for the egr system.What they did was disconnect your battery for the quicki reset for vehicle, thats why your radio had reset.

Hi. The best action in this situation will be to run the codes. This can be achieved by taking this vehicle to a local auto-zone, or dealership. I recommend auto-zone, they will run a diagnostic scan for free. Once the Vehicles CPU is scanned, it will isolate the actual issue that is causing this hesitation, and low idle. Running codes will prevent you from wasting money on parts that you don't need to purchase. The scan will give you an accurate print out that will inform you of the failing component.

sound like throttle position sensor.have it check out.also check air duct connected to mass air flow sensor and throttle body.if air duct is loose or off.it will cause severe hesitation.

check the fuel pump. could be going bad or stopped up....just a guess though, never really worked on a nissan. good luck!
