It runs fine at idle and when revving it but soon as you go in 1st(take in mind this is a 5 speed )
and get going it just falls flat on its face some times it’s second gear and sometimes third won’t go far enough to see if it will in fourth or fifth , recently ran it out of fuel also replaced the in pump filter sock and the fuel filter ,

 

It sounds like maybe the AFRs are incorrect when it gets under load. Do you have another airflow meter you can try? Have you already made sure there are no intake leaks?

You're not near NWA, are you? It would be cool to know someone on here locally.

 

Sounds like you're on the right track with the fuel filter and sock. Try that and report back with your findings.

 

The fuel pump and pump sock along with the fuel filter have been replaced idles fine still and picks and chooses when it want to act like it over loading on fuel or starving for it when giving it throttle and still won’t move more then 50 , it pops and smells really rich !! I’m from down in north west Arkansas

 

yes I have checked the intake for leakes and no I don’t have another air flow meter but if i unplug the pressure sensor for the air flow box it runs but does so rough but yes I’m from nwa live on the closer side to Oklahoma

 

We need to know if it's too rich or lean. I haven't experienced any popping while rich.

Have you checked the plugs and verified the timing is correct?

I have a couple spare N/A airflow meters I don't need. They both work. It sounds like you're local enough, you can have one and maybe narrow it down.

*Edit* Oh wait, it's an '88... Is this using an S4 or S5 AFM?

 

It’s running really rich and I believe the series 4 from what I got told when me and my cousin acquired the car we got told it was all stock it ran and drove fine up till it ran out of gas now it runs at idle just fine but soon as it under a load it’s just dies after 50 or so feet
edit)::! It pops and back fires and I wouldn’t know how to check time as I’m still new to this type of engine but it has good compression and runs soundly at idle but dies under a load

 

If you've got access to a timing light, clip it to L1 and point it at the crank pulley. There should be two marks on it, one for 5° ATDC and 20° ATDC. It's been a while since I've had a stock ECU, so you may or may not need to jump a service connector before you check the timing. Someone comment on this if you do. Anyway, L1 should be on the mark on the right. Then move the clip to T1 and make sure it's on the mark on the left.

Man, the fact that it's running rich is throwing me off. I would think if some sediment of something made it to the injectors it would run lean.

If you hold the flapper on the AFM at any angle can you get it to sound any better? I know you said it revs fine, but perhaps it could be better? Have you adjusted that little **** on the passenger side shock tower next to the pressure sensor? It's some kind of barometric sensor which allows you to adjust for different conditions depending on your elevation. IIRC, if you turn it clockwise it'll richen up, and vice versa. It looks like a giant flathead screw recessed in a hole. But probably not enough to cause drivability issues. Sorry, just thinking out loud at this point...

 

Your good man an no I haven’t tried that yet but soon as I do I’ll let you know but I’m just out side fort smith in van buren

but afm you mean the air flow meter ?
I sounds great just runs reallly rich and no I did not know anything about that I’ll have to give it a try and let you know

 

Really rich could mean a partially clogged primary injector. May be spraying enough fuel to run without a load, but not enough with a load. All the raw fuel would be getting dumped through the exhaust making it smell extremely rich.

You sure both rotors are firing?

Pull the plugs and snap some pics. Clean them, reinstall and repeat.

it was running fine before you ran out of fuel correct?

 

yes it was running fine before this started happening and I can’t tell if both are firing all these picture are soon as I pulled the plugs

 

it runs smoother further but still dies
under a load after 100 or so feet now

 

Those plugs look pretty crusty, probably not your issue but it would be a good idea ro replace them. Dont want to tell you to keep replacing parts but ive had cars that ran out of gas and it killed the fuel pump. Oreillys and auto zone should have fuel pressure testers you can rent. Check the fuel pressure as per the FSM which can be found at Foxed.ca . The next step would be to send out the injectors for a cleaning. Process of elimination, sounds fuel related. Start with the cheapest/easiest thing and work your way to the most expensive.

 

I am the new owner of this car. I have replaced fuel pump filter alternator battery leading and trailing coil packs. Just did plugs and wires. It will not rev past 1500 rpm. It sounds like it’s bogging down from the breather box. I can’t figure it out.

 

Have you or the PO even checked compression on this engine since it had problems after running out of gas?
