AboutRoland Finston Expertise I take questions about domestic Chrysler-product front wheel drive cars and minivans for the years 1982-2000 based upon my experience and shop manuals. I don't have detailed information (e.g. manuals) nor expertise for Jeeps, trucks, SUV's, import vehicles, or for years more recent than 2000 (except Sebring/Stratus I have '03).
I am available to take a question between 8AM CT and 9PM CT, and attempt to provide an answer within 1 hour. If I am shown as "maxed out" try again later in the day as I add question opportunities one at a time so as to respond quickly, but I do have other responsibilities as well so may not be available for several hours at times. Try at 7PM CT as I will always be available for one question then.
There are answers to hundreds of Chrysler questions at your finger tips: click on "view past answers", one of which may be to your question as well; or put a few key words in the "search for" box, above.
Experience I have been a do-it-yourself auto hobbyist for 5 decades, and most recently have been concentrating on the various Chrysler Corporation domestic front wheel drive cars and vans. I have shop manuals and wiring diagrams for many models for the years '83-'00, as well as rear wheel drive cars for the early 80's. I enjoy analyzing problems that other Chrysler enthusiasts are having and sharing my information.

Question 1994 chrysler concord, 3.5L. error code 43. car starts butdoes not run smooth and kills. have replaced computer, cam and crank sensors, coil pack, plugs and wires.some have said it simply needs 2 be reprograhmed and its in a limp or sfe mode.
Answer Hi Allen,
My 94 shop manual shows the 43 code is saying that one of more of the three primary spark coils is not drawing the correct current when it is activated. Because you replaced the coil pack I would suggest that you check the wires from the plug back to the pcm to be sure that one is not open or shorting to ground. They go to pins 17,18, and 19 at the PCM. Also check that the stem of the EGR valve is not stuck ajar as that will cause the same poor idle problem. Lubricate the stem with WD-40 where it enters the body of the valve and move it back and forth with the tip of a screwdriver in the slot of the valve stem.
Roland
