in neeed of some assistance..

[crowley12]

My 93 mark viii is having some issues.. it feels like its misfiring but I replaced the coils, wires, and plugs.. I cleaned the injectors, and the mass airflow sensor... Not quite sure what else it
Could be.. it seems like when I hit the gas the harder I hit it the more it wants to bog out.. its running real rich too.. tps sensor maybe?

Compression test?

 

[Dave 88 LSC]

Check fuel pressure. Make sure the pressure is good under load.
Fuel pressure gauge, tape it to the windshield and go for a drive. Should stay 32psi +

The compression test was my next step. It's just weird because one day it was fine the next it wasn't.. can it lose compression that quick..

 

[ASMBLYLINE]

Not likely unless you bent a rod or something but I would just check it so your nit chaseing your tail just in case.

What did you gap the plugs at?

 

[crowley12]

The plugs were pre gapped

 

[marco]

They have to be gaped at .054? I hope that's right!

that is correct. .054.
also, just unplug the maf sensor and see if anything changes.

 

[crowley12]

I'll check the plugs, and I already unplugged the maf it made it bog down even lower..

The IAC might be bad.

 

[Myco]

Could a plugged fuel filter cause this? I forget.

 

[gened33]

Check the fuel filter, fuel pump pressure and this is a long shot but the gasket and IAC module sometimes a small crack in it will screw things up. Good luck, Gene

If you have fuel pressure, replace the ICA like peps said.
