Hi all,I have a all stock 85 GSL-SE with around 160000 on the clock
It's my dd has been for 2-3 years.recent tune up fuel pump filter .just started randomly cutting out at any speed any gear any time of day.it may do it today may not for a few .the tac and other gages do not drop like a all out electric fail.it acts like someone flips the gas off for a split second.it bucks hard once or twice .
thanks don

 

I'm wondering if your leading ignitor is on its way out, or not making good contact.

 

Yeah, switch the ignitors around, see if your tach drops.

How does your fuel pump sound? Does it sound like it's struggling?

 

the fuel pump was new around 3000 miles ago.the fuel filter has around 4000 miles the plugs,cap and wired have around 6000.I drive it 64 miles round trip everyday all hightway speed.it cuts out like someone is turning the key off then right back on,so fast the car does not die just bucks hard .in fact its so fast the tac never drops nor do the indicator lights come on as if the power did turn off

 

go through and make sure the ignitors have a good connection. then look at the coils, make sure that all the wires are good are all tight. Then i would check the fuseable links make sure they are tight also.

 

Also, with the engine idleing and warmed up, open the hood and grab a hold of the wiring harness at the front of the engine that goes under the upper intake manifold and DEI chamber - give it a tug back and forth. If the engine RPM drops like it's running on one rotor, then you may have a fuel injector plug that's making poor contact with the injector(s), or possibly where it attaches to the wire bundle.

I had to buy two Borg-Warner fuel injector 'pigtails' for $7 each years and years ago when this problem plagued me. Simple fix - just splice them into the wiring harness where the stock injector plugs go, and you're back up and running.

About 30k miles since then, and not a single issue. Now at 208k miles. HTH,

 

I switched the igniters wires around and it still does it,I'll try looking at the wires around the injectors.I pulled the injectors and had witchhunter rebuild the a year and a half a ago.

 

I power washed under the hood and the issues stopped for now so I'm looking at the harnes around the injectors.

 

can you get me a part number and a location as to where to get them
