SOooo confused! help please

[Tyler]

when my engine is cold.. like mornings after sitting all night. i turn my car on. and hit the gas, and it feels like im misfireing so bad. like its only running 3 cylanders. but after about 15 min of driving.. all that missfireing feeling goes away..

could it be my dirty air filter? lol
or fuelfilter? or fuel pump?

i want to fix this..

like you will tap on the gas and it feels as though it could shut down? Its just because it is cold, mine does the same thing after it has been sitting for a long while. After warming up it goes away and i can rev normal. Nothing is wrong

it was never this bad before.

it seriously shakes like its running only 3-4 cylinders.. its bad!

THEN DONT TOUCH THE GAS! Let everything warm up for at least a few seconds, before you do some damage. Hitting high revs on cold oil is very bad.

lol.. but im always in a rush to make it to school on time every morning! [img]graemlins/crybaby.gif[/img]

If it has been a long time since the air and fuel filters have been replaced, then change them. If you still have the misfires, give it a good tune-up. It shouldn't be misfiring like that when it's first started. You need to get it fixed before the problem get worse.

GM service manual says for 96 camaro
"Knocks Cold and Continues for 2 to 3 Minutes
Engine flywheel contacting the splash shield. Reposition the splash shield.
Loose or broken crankshaft balancer or drive pulleys. Tighten or replace as necessary.
Excessive piston to bore clearance. Replace the piston.
Cold engine knock usually disappears when the specific cylinder secondary ignition circuit is grounded out. Cold engine piston knock which disappears in 1.5 minutes should be considered acceptable.
Bent connecting rod. "

Knocks on Start-Up but Only Lasts a Few Seconds
The following conditions may produce engine knocks on initial start-up, but only last a few seconds:

Improper oil viscosity.
Install proper oil viscosity for expected temperatures.
Refer to Maintenance and Lubrication.
Hydraulic lifter bleed down
Clean, test and replace hydraulic lifter, as necessary.
When the engine is off, some valves will open. Spring pressure against the lifters will tend to bleed the lifter down. Repair the lifter only if the problem is consistent.
Engines operated for only short periods between start-ups may have lifter noise that lasts for a few minutes. This is a normal condition.
Excessive crankshaft end clearance; Replace the crankshaft thrust bearing.
Excessive front main bearing clearance; Replace the worn parts.
Timing chain tensioner malfunction; Clean, inspect and replace the timing chain tensioner, if required.

dude it's just general aging of the car most likely. I have a similar problem with mine but it's with the transmission. If I take it out to drive for the first two minutes w/o letting it sit and warm up it'll be reluctant to shift and when it does, it shifts HARD...HARD enough to knock my foot off the gas...probably could chirp them tires if I actually went WOT...

Mine was doing that when my O2 sensor was going bad. No codes, just really rough idle and sputtering.
