If you have excessive white smoke coming from the vehicles exhaust, it sounds like your headgasket is failing. Especially having a rough idle too. Check your coolant level, does your exhaust smoke smell sweet, like Antifreeze? If so, the gasket has blown. Hope this helps...

Car starts hard runs good on highway stalls if i dont keep my foot on gas have to push gaspeddl to floor to start replaced plugs wires also idle control in throtal body


So IAC has been replaced. Sounds like a dirty throttle body, EGR valve, or vacuum leak. DId you do the maintenance yourself. If so then you should be able to inspect Throttle Body to determine if black and dirty.. this can cause intake problems leading to your issue adn rough idle. EGR valve sends exhaust gas back into combustion chamber to reburn it and make car more environmentally sound. If stuck open it can allow too much exhaust into combustion chamber causign a lean mixture, too much air can cause this.. Vacuum leak can also allow too much air in. Start with easiest and check Throttle body, then EGR valve, finally for vacuum leaks. Depending on your skill the EGR can be cleaned as can the throttle body.. a good link for TB cleaning is http://www.popularmechanics.com/cars/how-to/repair/1272341. A vacuum leak may be harder to diagnose. You are compensating by depressing gas pedal telling ECM to send more fuel to motor to overcome this issue thats why it will run and start with gas pedal pressed.

When i start the engine it will run at about 3000rpm .i checked the cables at the carb and the gas.what else could it be pedal


Check for vacuum leaks. Check PCV hose and other vacuum hoses. Spray carb cleaner around intake, throttle body and vacuum hoses while idling in park. If spraying anywhere causes a change in idle. that area has a vacuum leak.
Possible IAC motor dirty or defective. Remove it. Clean the IAC plunger tip and the throttle body passages with air intake/throttle body cleaner spray can. Reassemble and start vehicle.
