1984 Corvette- hesitates when cold-stalls and won't start till it sits a while- if you get on it in a corner it will fall on it's face but not stall-surges at low speeds

Car is well tuned- new plug wires - cap - air filter - plugs- it hesitates when you excellerate and runs erraticly at low speed--car has been sitting for 3 months and now has this problem Car is well tuned- new plug wires - cap - air filter - plugs- it hesitates when you excellerate and runs erraticly at low speed--car has been sitting for 3 months and now has this problem

I havent hered any solutions yet--the sight is running me around in a circle I havent hered any solutions yet--the sight is running me around in a circle

Hello! You did not mention the fuel filter; Is it fresh? let's check the Throttle Positioning sensor (TPS)...It is bolted to the throttle body...Has a three wire connector...Colors are...Dark blue...Gray and Black...Take two safety pins and push them into the rear of the connector with (connector in place) on the Dark Blue and Gray wires...Set a voltmeter on the 2 volt scale...Hook the + probe onto the Dark Blue...And the - probe on the Gray...Turn the key on...Must read less than 1 volt (.85)...Start the engine...Slowly increase the throttle...Voltage must increase smoothly to 4 volts at open throttle...If voltage jumps or acts erratically the TPS is defective...

Also inspect the air inlet flap for carbon build-up...Throttle inlet should move freely...

Remove air inlet hose and inspect the Mass Air Flow (MAF) sensor...It's between air filter and throttle body...Look for dirt/debris on the screen...

Last; Bury a can of Sea-Foam at local auto store ($9) and pour it into the gas tank...Excellent product for removing carbon build-up...

Let me know what you find.......saailer
