Having problems with your 1997 Pontiac Trans Sport ?

Vehicle Starts, Idles Erraticly and Stalls

\015 The van is a 1997 Trans Sport Ext. w/ 3.4L\015\012\015\012The van will start and sputter, the idling is very erratic and it will eventually stall.Usually after this happens it will crank, but wont even bother to start until it is completely coolBright and early in the morning when it gets the first start of the day it starts like nothing ever happened.Sometimes while driving the dash cluster will go crazy, service engine light comes on, battery light comes on, abs light comes on and the speedometer/tachometer will jump up and down, power steering & brakes shut down.The van begins to sputter and eventually will stall\015\012When the vans acting up (Ex. In the middle of the street.. very frustrating) it will stall, when and if it decides to actually start it sounds HORRID.. sounds like an old backfiring hoopty. Its not so much coming to a stop or anything when it wants to stall its just very random.\015\012Changed: Alternator, battery, TPS sensor, crank position sensor & camshaft sensor.Fuel pump kicks on before start, there is also fuel pressure.\015\012I, as well as my uncle (backyard mechanic..hes been fixing my cars since I began driving, hes very good) is baffled.. hes the one who suggested the crankshaft/camshaft sensors .. and when I looked up the symptoms of those components it was BANG on .. and I was thrilled thinking the van was gonna be fixed 500 dollars later.\015\012Definetly not.. Ive stuck by GM and will argue with a ford owner till the very end about who's better.. but this 3.4 is starting to make me think otherwise.\015\012Should have never got rid of my 3.8L Monte Carlo Z34 :(\015\012Any help would be greatly appreciated.. I would ask an expert but my bank is just a little place and my card wont work in online shopping.\015\012Thank you\015 Posted / edited by AnonymousUser on : 16-09-2019
