Car has the hiccups and rough acceleration!


Go to autozone they have a free OBD 2 code reader. Start by finding out what that code is. It might be something as simple as an O2 sensor. Hope this helps.

1985 f150 rough idle


An exhaust manifold leak would not case it to run rough. Check vacuum lines that go to the in take manifold. If you have a line that is open it will get too much air at idle and cause a misfire intermittently. You also need to check plug wires. How long have the plugs been in the heads. Check the rotor and cap also.

Why is my 1994 Chevy S10 Blazer lugging? motor shakes and lugs.


Could be vacuum leak or bad ignition wire(s).

I had a similar problem on my "93 Ford probe. The engine idled pretty rough with shakes, Turned out to be a head gasket leaking engine coolant into the cylinder during low rpm's. At fast rpm's it was fine becuase the internal cylinder pressure was greater than the hot coolant pressure & would prevent the coolant from leaking in.

A friend has the same problem with his "94 Blazer 4.3 L, throttle body injection, manual tranny. He hasn't fixed it yet, It started a few weeks ago & is getting worse. His gets a fast idle with hiccups which causes the engine shake. He already checked the EGR valve. He also has a severe exhaust problem, Not oilly but very gray & terrible smelly, but only when the fast idle problem happens. THis fast idle hiccup problem starts when the engine is warmed up.
