Hey guys, I'm a long time lurker, first time poster. I have a 98 Frontier with a 2.4. Purchased the truck fairly cheap almost 2 years ago, and have had 0 major problems. I love this little truck, but I'm lost as to what to do now.

2nights ago, I drove about 8 miles to the next town over, and pulled over in a gas station parking lot. I never shut the truck off, but got out to use the atm and got back in. When I went to pull back out, the truck almost died. It was missing and sputtering if I tried to apply any gas pedal. If I was easy on the pedal, it went fine. It also sounds like a backfire is coming from the throttle body area. Never had this problem until leaving that parking lot.

I have a 99 with the same engine for parts. I first bought and replaced the fuel filter. It was dirty, but nothing out of the ordinary. Still running bad. Went and got a code scanner, had p1105. Pulled and tested the sensor from both trucks, mine was faulty so replaced. Still ran bad. Got home, read codes again and see p0105. (I may have the code numbers backwards) So a friend, suggesting it's starving for fuel, swapped the fuel pump from the other truck. No go. We've swapped and tested several different parts and had 0 luck. The MAP/Baro solenoid valve is applying vacuum. Any other ideas, guys? I'm beyond frustrated. Sorry for the wall of text, just wanted to be thorough. Thanks in advance for any ideas!!

Timing? Check and see if the distributor is loose.

 

[JoshA85]

Distributor is tight. Checked it when I removed cap and rotor to check them. I'm just at a loss with this thing.

How old is the timing belt? Sounds like how one of my Subaru's started running when it jumped timing.

 

[JoshA85]

I believe it has 2 chains, but they're factory as far as I know. The truck has around 130k miles. I guess I'll have to pull the valve cover this weekend and see what I find.

These have a Timing Chain...but, if it or the distributor failed/slipped a few teeth = would explain your symptoms.

 

[JoshA85]

I believe I know the process for checking to make sure the distributor hasn't slipped, but could you explain? Is it rolling engine until #1 is TDC on compression stroke?

Fuel or Air issue?

Check here:

Problem 4: Engine Hesitates, Stumbles, Lacks Normal Power

or this:

Problem Engine Hesitation

 

[shift_RUSH]

Procedure prolly in here somewhere. No help here since I sold my truck w/ original distributor at 185k miles.

Sounds ilke a fuel pump, but since u said u swapped it out, did u check ur MAF sensor?

 

[smj999smj]

I would get a fuel pressure gauge and confirm the fuel pressure is within specs to eliminate that as a potential issue. Then, I would perform a compression test to the engine.

 

[roastbeef]

i had a similar problem, but i had a long crank to start the truck when it was warm, then it backfired. turned out to be the fuel filter.

 

[JoshA85]

What's the best way to test fuel pressure on these trucks? I haven't found a port on the rail..

There's no way to tap into the feed line to the rail as far as I know. The only thing I can see the that can be teed into is the return line, which is kind of pointless

I check mine by teeing in just before the fuel filter

My brand new pump was putting out about 26-30 psi I think, which is low, but I've been running it for a few years. Thinking of getting a walbro pump

I encountered the exact issues like you stated on my 98'.

First time it happened I was driving in the rain shower. Not sure what happened but my truck was hesitating and sputtering bad but the next day she ran fine. This happened a few more times with the same result.

The other time it happened I tried the following :

- Clean the MAF (didn't help)
- Replaced with brand new NGK spark plugs (help slightly)
- Replaced with brand new NGK spark plug wires (fixed my problems)

The old spark plug wires that were on my truck was roughly about 45k miles from Autozone.

Hope that helps

I had a vehicle that did this and it was a small crack in the distributor cap.

 

[JoshA85]

My plugs and wires aren't maybe 3-4 months old, so I haven't really thought of that. I'll have to look into that though.

The only thing different about what you describe is that once it started on mine, it never quit. It only lessened when I advanced the timing as much as I could.

Not sure this will help or even apply:
When my Gen 1 distributor cap would allow condensation to form inside, I'd encounter very challenging restarts IFF I did not drive at least a few miles upon the initial start of the day. A new distributor cap fixed this issue every time.

 

[rollthelosingdice]

This exact thing happened to me when I was driving. The screw wasn't screwed in tight in the rotor and came out. I can bet anything it's your distributor or timing. Try a new cap and rotor. Fixed a stalling issue on my honda too.
