Escort :: 1988 EXP Rough Idle - Fuel Coming From Injector
Apr 29, 2012
I have an '88 EXP Escort with the non-HO 1.9L
I was noticing a rough idle (vibrating, sounded like it was bogging down)
I changed the plugs, wires, cap and rotor. Still happening.
Noticed that my o2 sensor was unplugged. Plugged it back in. Still happening.
Went to check the air filter and noticed the insane amount of fuel that was coming from my injector.
I am getting horrible gas mileage (8-12mpg)
Here is a video of what I am seeing: [URL] ....
What would be causing that much fuel to be sent out?

My new 2015 Sonata 2.0Twith 8000 miles started running oddly about 2 weeks ago. Rough idle with engine "sputtering". Erratic acceleration -- merging into traffic on highway and car not going over 40mph, even with gas pedal all the way to the floor. On deceleration, clunky down-shifting. Very hard to drive. Dealership first came back with diagnosis of "buildup on throttle plate" (Note - I use only high-quality gas AND only have 8000 miles on car, 3500 or that being one long highway road trip). Then, after 3 days of diagnosis, they say I need 2 new fuel injectors I am baffled how a new car can have either buildup or failed fuel injectors...

Having a rough idle on a cold start. After some research and closer inspection of the vehicle, I'm quite certain I have at least one leaking injector that is flooding a cylinder and causing the car to misfire on a cold start. I'm also not at the gas mileage I should be at.
So I'm wondering, is fuel injector replacement as straightforward of a job as it looks? Any major issues I could run into in doing a replacement?
I'm planning on replacing all six injectors (I can get them for $50 each buying online with a discount code), but given that the vehicle is so old am I better off just replacing the faulty ones? I'm assuming pulling the spark plugs and seeing which cylinder is wet will tell me which I need to replace.
And one more question: Is there a way to depressurize the fuel system when I park the car for the night, thus preventing fuel (or most of it) from leaking into the engine until I get this fixed? I've read that just unscrewing the gas cap can depressurize the system.

I have a hard starting condition after warm up. It starts up fine when it is cold.After running diagnostics and coming up with no error codes, I noticed that I smell raw fuel after the car was warmed up and sitting for about 15 minutes. I believe this is the cause of the hard starting condition after warm up.
How do I test the fuel injector for leaking? I think it may be leaking fuel into the throttle body after sitting for a few minutes, causing a rich or flooded condition which makes it difficult to start after it has been warmed up.

So I turn the heat on, and my engine feels like it's going to stall out, the RPM's drop by 200. What could this be?

The car has 269,231 miles. A few days ago, my wife said the lights began dimming, the fuel indicator needle began dropping and rising and the low fuel light came on (with 3/4 of a tank). Thinking it was some kind of electrical issue, I took it to the local parts store and had the battery, starter, alternator, etc, checked. There was a little corrosion build up on the positive battery terminal but everything else checked out ok.

my excursion just started hard and had rough idle one morning then code P0270 - injector, FICM or wires between are the logical choices I think.
started with wires - all connections good at FICM and injectors (applied dielectric silicone) - checked all 4 wires from injector connector pins for resistance with omh meter from X-1 connector. no change
so next is FICM. couple years back sent to ed for repair. if I remember right it was power supply side only so the "brain" side might have gone? good news is could I get a loaner FICM off fellow 6.0 and installed (can't confirm condition of loaner - trucks been parked a while) same code same cylinder - no change.
I read somewhere possibly swapping two injectors (say 2 and 4?) and see if the code follows the injector or stays with the cylinder, further test for a bad FICM
Is that necessary? I would hate buy and replace the #4 injector just to put it back together to find no change then forking over 6 7 hundred more on a new FICM.

I bought this truck a few months ago. After trying everything under the sun to try and rectify a poor running problem, it was realized that injectors needed replacing. Ended up putting in 160cc/30% unlimited diesel performance injectors. The truck has a rough idle and surging problem. After trying to install the chip from gearhead, the truck didn't run any different, ultimately (according to the shop doing the install) smoking the ECU. New stock ECU, same problem. Goes good under throttle, just idle is bad. I get weird looks at the gas station. People think it has a big cam.

2012 F-150 5.0 Rough Idle Upon Start up - YouTube
Whenever I first start my 2012 F-150 with the 5.0, it idles rough and if I step on the gas it acts like either an injector is cutting in and out or it's missing. It doesn't really seem like a miss though, more like an injector/fuel issue. What it could be. If I let it sit and idle it won't go away unless I step on the gas and get it > 2500rpm or so.

Its an 88 F-250 4x4 with a 302 EFI 5-speed. Fair compression, runs smooth. When I press the gas pedal it takes about 5 seconds for the old girl to return to idle. I know nothing about EFI. My buddy,s out of town with the hand held mechanic. Is there anything I could check till he gets back.

1988 F250 351 5.8
I've worked for months on this truck and I now have it in the shop. The truck shows a 41 code and has a lean miss at idle that get worse during acceleration and cruise. The injectors were refurbished 6 months ago and the ECM was replaced 3 months ago. All sensors are new and within specs. Fuel pressure is good and there are no vacuum leaks.
The mechanic has verified that the condition is not electrical related. The O2 sensor will react if carb cleaner is sprayed into the throttle but other wise shows constantly lean. He's now checking all pins at the computer for any off condition. He is suspicious of the refurbished injectors. I'm wondering if the computer somehow went out again. Which way to go or what/how next to test?

I have a 94 F250 5.8 liter with 96K miles. Can I remove the fuel rail and clean or replace the filter that is placed at the top of the fuel injector?

Working on a 88 Ranger 2.9L 5-speed ext cab. The fuel pressure drops off fairly fast when turned off and I'm pretty sure that the check valve is bad. My question is, which pump has the check valve? It is a single mid tank set-up and has a pump in the tank and on the frame.
Pressure is fine while running. about 30psi @ idle and 40psi with no vacuum on the regulator. The pressure drops off within a couple of minutes which causes it to have to crank over for a bit to rebuild pressure and start.
It looks like the frame pump is readily available while the in take pump is special order. I just need to know which one has a check valve. I'm thinking the in tank pump, but I hate to waste money for the wrong pump.
Pressure drop rate
30 psi @ shut off
25 psi @ 1:05 min
20PSI @ 2:30 min
15psi @ 4:45 min
still dropping

I have a 1988 Ford F-250 Lariat, 7.5L 460, four-wheel drive. I have two fuel tanks on it, and I've been having a really annoying, obnoxious problem with it lately. After running it for a while, I noticed that I keep losing fuel pressure, and the truck stalls. When I try to start it, it does nothing but roll over. It just won't start. I've changed the fuel filter, I know both fuel pumps are working (I turn over the key, I can hear front, back, and high pressure pump attached to the left side frame rail kick in.) It's Fuel Injected, not EFI, hence that third pump. The problem happens a lot, and it's random. I could drive for 100 miles, stop to get something to eat, come out, and it won't start.
I thought maybe it was the fuel pressure regulator, but I don't think that's the case because it still runs. I would assume that if the regulator was bad, it wouldn't run at all. I also thought that maybe it was the relay, but according to some mechanics I spoke too, if I can hear the pumps kick in when I turn the key over, then the relay is fine. The only thing I could think of is that it might be the fuel selector switch. Maybe it's going bad, shorting out or something. When I flip the switch though, it switches between fuel tanks, and the gauge reads how much fuel is in it from the sending unit.
There's a schrader-type valve up by the fuel injectors. When I push it in, it barely squirts any fuel out, if at all, so I know the pressure is low. When I push it in on a good day, it sprays out like a water fountain. Just tried starting it again - no good. Pushed on the valve, it spurted out some fuel pretty well, but still won't start. Occasionally tries to, but ultimately won't. I know the spark is good, checked the plugs/distributor cap. Can't get the sucker to start.

I've been having a curious issue with the engine in the Passat. When I put gas in the car, it generally is hard to start and stalls. This happens once or twice, and then the car runs great. Sometimes the check engine light will come on, but I haven't been able to read the codes. The mechanic said that the car was driveable. I am curious for potential causes and solutions?

Yesterday I started up my Phaeton after it had been sitting for about almost a week. When it turned over it had a rough idle and also a fuel smell, as I drove it the idle went away. However I have never had this happen before and the fuel smell concerned me.

Ok new issue that started yesterday only get it at idle. Runs great above idle no real power loss or change in fuel econ. Haven't really had a chance to test much. I was thinking maybe a injector issue but I don't know

I head out to work this morning and truck drive fine. I do not get on it. I cruised on the highway for 12 miles at 70 mph. I get to a traffic light and then it begins to idle rough and my fuel pressure gauge reads 0. I replace both filters over a month ago and did the blue spring upgrade at the same time. I've put over 2000 miles on the truck since then without issues until this morning. Also the fuel pump was replaced by the dealer a year ago in July. No check engine codes. Where do I start looking?

I have been experiencing some issues with my '06 rio5 (same engine as your hyundais). this forum is way more active than the kia forums, so figured id give it a shot here.
I am experiencing a rough idle at start up while the car is low on fuel (<1/4 tank). it idles rough for a few seconds, the check engine light flashes a bit, and then it runs fine.
The car is an '06 rio5 with approx 19k miles on it, five speed manual. Also, sometimes after refueling and it will just shut off while waiting at an intersection. Not sure whether these two issues are related, but thought i would mention it just in case they were.
