When I smoke the motor smoke comes out of my Egr and iac SolvedSolved

Ford F-150 1999 5.4. 4x4 232000 miles
Smoke comes from the Egr not gasket issue it's coming from under the top part where vacuum hooks up to also smoke comes from iac looks like it's coming from the little round part on side and also from unit itself.do these parts suck outside air or are they leaking. Also truck has code p0171 lean on bank 1 that I can't figure out. Any help would be appreciated. I also started the truck and tried the o propane gas bottle and carb cleaner and sprayed it around both WITH no change in motor running. Not sure what to do next except change plugs injectors and coil packs and see if that will solve my p0171 code.

I just had this problem as well. I took truck into garage and had intake gaskets replace new hoses and new intake. This cured my issue. Certainly something you may want to have looked into. Job was a little expensive but it was well worth it and I got a great deal on it. They found my intake was cracked, the tube behind intake had somehow broke and was leaking coolant, My truck shook at idle and take up with little power. This job can cost at much as $2000 but it was 1/2 cost at my local garage. I just got truck back and Its like its brand new. Good luck

Thank you I smoked the motor again and now have no visible leaks anywhere and we smoked it good so now I'm thinking I've got bad sensors.

Starting

My car won't start but there is no error code provided, injectors are clean, ECM signal is negative and there is spark in every spark plug. What else should I check?

The computer sends a pulse to the injectors, so you could try with a different computer and see what happens.

My pick up does not accelerate

Ford F-150 1998  140000 miles
It started with jerks while driving; when starting gold y vibrates and then it normalizes. While driving it losed power as if choking a little, but now it got worse. It chokes while accelerating and sounds as if exploding, when I let go it keeps driving; if I accelerate again it does the same but it doesn't stall. If I turn it off for 5 seconds it works for 10 minutes and then it fails again. I alreadi cleaned the injectors, changed spark plugs, air filter, fuel filter, fuel pump, coils and their sensors. I've already had this problem for a year and they can't solve it, yesterday I scanned it and had air sensor error, but changing it didn't fix it.

It sounds like the issue I had with my 2008 5.4l engine. I replaced spark plugs and coils. Finally it ended up being the VCT solenoid. I got my power back and it runs great.

Injectors not working

Ford F-150 1993 F150  168000 miles
Fuel pump relay not pulling in if I jump it out fuel pumps will run, if I spray gasoline into intake engine runs fine seems like I'm not getting any injector pulse what part would give the PCM the input to allow injector pulse any help appreciated thank you

If the fuel pump relay is not pulling in and you are not getting any injector pulse, there could be a problem with the PCM (powertrain control module) or with a component related to the fuel injectors.
Here are a few things you can try:

Check the fuel pressure. If the fuel pressure is too low, the injectors may not be getting the fuel they need to function properly. Use a fuel pressure gauge to check the pressure at the fuel rail. The pressure should be within the manufacturer's specified range.
Check the fuel pump. If the fuel pump is not functioning properly, it may not be able to provide the fuel pressure needed to activate the injectors. You can test the fuel pump by listening for a humming noise when the key is turned to the "on" position.
Check the fuel pump relay. If the fuel pump relay is not functioning properly, it may not be providing power to the fuel pump. You can test the fuel pump relay by jumping it out, as you mentioned.
Check the wiring. Check the wiring harness and connectors for any loose, damaged, or corroded wires. Make sure all connections are secure and free of any visible damage.
Check the PCM. The PCM is responsible for controlling the fuel injectors, and if it is not functioning properly it may not provide the necessary input to allow injector pulse. You may need to have the PCM checked and possibly replaced.
I recommend having a mechanic diagnose and repair this issue to ensure that the problem is properly addressed and the vehicle is safe to drive.

I have a 1987 Ford F-150 that does the same thing. After it warms up, the engine sounds like it’s not getting fuel.
Inkman66 from Canada 4 years ago
I would check all the vacuum lines, and take a look under the ‘tomatoe juice can’ too...most likely a leak, possible the bottom of ‘the can’ has rust holes in it. If not the problem, the next place to look is to see if egr valve is dirty or has a hole in the rubber diaphragm on the bottom of egr valve itself.

Ive checked vacuum lines and replaced spark plugs wires distributor aswell still cant get it to run right drives just fine for about 3 min and then starts in limp mode for some reason

You can just rip the whole system out of the truck. All the boxes are the antenna in the steering wheel in the rear quarter panel of the driver side.
There may be more but that's what will allows my truck to run. I have a broken steering lock And no Ignition switch. It is supposed to have a key fob. But I do not have those keys anymore. It's still runs just by. I took all the boxes out. And that's where I'm at with it.

Engine failure, carbureted F150

Ford F-150 1987  150000 miles
Hello! I just bought a carbureted V8 Ford F150, but the problem I have is that it lacks acceleration and the engine vibrates the same as if the injectors were clogged, but obviously it is carbureted. What I haven't checked is the timing with spark plugs and cables. It was already without use for over 3 years, and to add more information it doesn't produce smoke or makes weird noises, and when it is in parking and you throttle the engine it sounds as if something was uneven.

The cables might damage for all the time it was parked; change the spark plugs too and check the distributor cap and the fuel filter
