95 transport 3.1

i been haveing a problem with the van for about a mouth sometimes it drives fine with little misfire but other days it misfires real bad and hard to accelerate but comes out after a cpl mins it shifts fine i thought in might of been tcc i disconnected the plug ran the same. other problem is my tach bounces but doesn't sound like the engine is reving higher when it bounces i pulled the codes but can't find my book the were 32 34 43 i know 34 is the map sesor but not sure on 43and 32 thanks in advance

thanks lmp for the code sheet today i earsed the fault codes to see if the came back.i drove a distance 50kms only code that came back was 32 egr so i'll do some more test tommorow or go to my friends salvage yard if we don't get to much snow tonight to see if he has any to try before shelling out the big bucks

faulty EGR valve might cause starting problem if it stayed open but in normal operation, EGR faulty operation has no operational consequence....so I suspect you have an ignition problem...the ignition module is a common problem with this model so if yuo go to the scrapyard, I'd look for this part ..hoping the one you'll get is better than yours. ALso make a voltage measurement cause some symptomsyou describe look like low voltage problem (alternator failure)...but you'd know about that cause the battery would eventually go dead.....
