Engine hesitates at low speed. Could ignition wires be the culprit. Vehicle has 85000 mi and still the original wires

I guess most people would tell you yes, on the wires. I do not consider them preventative maintainance,as you would spark plugs. Nor do I ever replace a PCV Valve,they don't fail and only regulate air flow from the crankcase. Education will save you money.
I have run three vehicles 17 to 18 years each, on OE Wires.
I only replace parts, if they fail a test. Yes, I diagnose and test,everything,always. Not every professional does that,as you probably have found out. I see repair orders all the time, from dealers,that never road test a vehicle. In & Out Mileage is the same.

I would lean toward ignition,check for vacuum leaks,effecting the O2 Sensors,check fuel pressure,with the gauge taped to the windshield on a road test.
Check TPS Sensor data.
Simply cleaning the MAF Sensor and having a clean Air Filter may be your only problem

Never assume professional service was done correctly or addresses why you went there in the first place.
You need to dictate what you want done and what problems you expect to be resolved
I would never go the a dealer,not necessary and costs too much.

Ignition wires are part of a tune up. if the wires where bad you would see sparks on them at night while you engine is running. or you can take a voltmeter to them and that will tell you if they are good.

1999 SL2 engine just suddenly dies while vehicle is in motion at various speeds and intervals of distance. (.3 to 1.5 mi ) Just recently began fix-up on this car. Standard ignition tune-up, wires, plugs,...

I had 4 saturns, a bad crank sensor mounted in the block behind the starter was the fix which matched your problem. When you get the starter out, replace it too as you will not want to go in there again.

When accelerator is applied it wants to hesitate and power down-seems like it isnt getting fuel or no power tio the engine-could it be points ned replacing?

That might be the answer if your truck had points. Points have not been used in automomotive ignition systems since the late 70s. The maintenance schedule for your vehicle does recommend replacement of the fuel filter, spark plugs. distributor cap, distributor rotor, and ignition wires every 60,000 miles. Hesitation can also be caused by a dirty Throttle Body bore. If the Check Engine light is coming on, I would recommend having your Engine Control Module scanned for fault codes and if any fault codes are present,have the code/codes properly diagnosed before replacing any parts.

Miss at low speed 1999 lesabre. Changed plugs about 10,000 mi ago. Seems to run fine at speed. 90,000 mi

If you only replace the plugs, you need to go one step farther. The wires on today's cars are more important than the plugs. The ignition systems are high energy and when the wires get old they build resistance. This causes the energy to not reach the plug. Make sure you use Delco wires. If you do you will get another 5-10 years, If you use a cheap brand, you will need to replace them every year.

Hope this helps.

also do a fuel injection clean.

Look for a broken or missing ground strap between the engine and the vehicle frame.

If you can't find it - or suspect it is damaged - temporarily connect a heavy gage wire or wire braid between a metal part of the engine and the NEGATIVE battery terminal. Take it for a spin to see if this helps.

Good luck !
