Asked by jason Jan 17, 2014 at 10:30 PM about the 2000 Chevrolet Silverado 1500 LS Extended Cab 4WD

Question type: Maintenance & Repair

it got very cold then above freezing with heavy rain. it started to run rough during the wet weather. and now that it is in the low 20s and teens it is sputtering badly when I accelerate. I am at 200k and due for plugs wires and oil. its a 5.3 and also CEL flashes while accelerating. all I can say is WTH is wrong?

these have a fragile wire that does all the heavy lifting...is a bit like a tungsten filament...they will break~

OK I changed the MAF/IAT and it made no difference. even cleaned the permanent filter. Should the IAT be separate or a unit. I miss my smooth running truck. Help anybody
