Having problems with your 1999 Chevrolet Silverado 1500 ?
I have a 99 chevy silverado. It started acting up, have to floor it to get it started and then idles real rough, if I hold the gas down after started for about 5 secs it will finally register and rev up but if I keep it constant at 3000 rpm, it will stay for couple secs then idle down and down with gas still pushed. Also idles at 250 rpm and extremely rough. Recently replaced fuel pressure regulator. Fuel pressure tests at 40 psi in on position and about 45 psi when trying to start/idle. Any ide
Maby it could be your spark plugs or even the fuel pump itself could be going bad and not pushing enough gas through
Check for any bad vacume lines or lose power cables. Are there any truble codes you can rent a code scaner at any autozone (you get all the money back when you return the scanner). If its a 4.3 you could have bad camshaft sensor. 4.8 and 5.3 you might have bad spark plug wires or cam sensors as well.Hope this helps. get the codes read and get back to me with more info and we will figure this out.
