I have 360K on this baby so help if you can. Car starts every time, new plugs, wires, rebuilt distributor, cleaned EGR, cleand and tight all grounds, checked for some but not all vacume, ran high octan, with lucas gas treatment still back running. it was intermitant last week and I missed work today because it has been 2 days of this now any thing will help thanks

 

forgot to add that the codes are 1 flash o2 sensor and 4 long flash with 3 quick flashes, my book doesnt list a code 43 so not sure what is going on

 

Codes 1 and 43 are related and 43 is listed in OEM manual. It's code usually indicates faulty O2 sensor. There is an extensive diagnostic. If you haven't done so, download one of the applicable manuals (90-93) from Online Manuals post in DIY forums.

good luck

 

Started theO2 diognostic and when it hit me new plugs don't always mean they are good. Pulled plug wires one at a time, got to the second wire pulled the cap and had no change in RPMs. Since I know all the wire and cap are new, I swap plugs between #4 and #3 and ill p
Be a pig in **** if it isn't just a fouled plug. But thanks for the O2 info would have pulled my hair out with out it

 

Thanks for posting fix.

Watch #3 for a recurrent problem. Oil fouling the plug (poor oil control rings) or leaking coolant causing miss are possible, but less likely.

good luck
