helpp my car does not accelerate smoothly

its my 02 zx3 109k mi never had an engine problem it started to get a little sluggish in the winter very hard to start sometimes

BUT NOW it jumps around like a horse I need to jump on the gas so it wont stall out and then once I get it going I need to keep my foot reallllyyy steady or it will start bucking again
the idle isn't too rough

so here's what I did in the recent couple weeks of this problem since the starting issue
changed the battery
cleaned the maf
seafoam through the vacuum line
fuel injector cleaner
changed the wires one happened to be busted at the boot still doesn't drive smooth
and then I pulled the spark plugs and the middle 2 sparkplugs had oil around the rings none on the tip I changed them all but still the same problem


I would also like to change the fuel filter and air filter but haven't done so yet



the car is stick its got a aem cai, borla exhaust
I use the copper plugs also have a spark plug cover so maybe that caused my valve cover to leak?

IAC
Located on intake sideways, and under, by the starter. Take out the Two 8mm bolts, from under car.
Take out airbox & big air hose to throttle body to access the lead wire and pull the IAC up and then unclip & clip on new. Lower unit back in. Go back under and "feel" install it.


Restore proper idle to your engine with a new Idle Air Control Valve/motor.
The IAC is a key component to your engine's idle speed by allowing for air to bypass the
throttle plate. A bad or malfunctioning idle air control valve/motor will often cause a
variety of symptoms such as engine stalling engine stumbling and irregular fluctuation of
engine idle speeds.

I'd add PCV hose to the IAC swap advice. They tend to suck flat at the bottom bend. The replacement part has a slightly different design that's supposed to prevent recurrence.

Ok Ive been on Spring break. So haven't done anything yet. But Ive looked into changing my pcv but I can't fond it. I know there's 100 different threads on finding it. With my aem CAI I think the previous owner maybe bypassed it or somthing? There's only one single hose running from the valve cover to like half way down the intake with. Nothing inside the hoses

If you know there's a 100 different threads on finding the PCV then READ them. You just might learn that the PCV line goes nowhere near the CAI..................your mentioned line is the other half of the system. We can't tell you where the PCV is, you won't read this post either..................krikey

IAC? OP clearly says the idle not too bad. IAC has nothing to do with power up and away from pure idle speed. Idle ONLY.

Coil pack like said before, they are a tuneup item on these cars and commonly crack to miss under load. Coil connector lead commonly cracks and frays right at the connection too. Hard to see sometimes. The entire ignition system on these must be kept tiptop or problems quick.

If original fuel pump the pickup filters could easily be stopped up at that mileage, sorry, the tank comes down to get to those. Or cut access hole under back seat.

looking at engine, pcv box is on right side near tranny. look at that line: http://www.ebay.com/itm/MOTORCRAFT-E...#ht_1998wt_987

You can JUST CLEAN IT! As well as MAF, IAC, TB and your battery body ground strap.

Spring break? Lucky. We are apparently not getting spring here this year. Woke up to a fresh 10cms (4 inches) of snow.

The valve cover gasket is known to develop leaks. Unlikely that a plug cover would contribute, unless it's badly fitted. Just replace the gasket now while you're thinking of it and it'll be good for another hundred thousand miles or so.

If you look up from underneath your car as though you're changing the oil filter, you'll see a black hose a few inches above and to the left of the filter. That's the PCV hose, and in all likelihood it's flat at the lower bend and/or has a hole. If you have long fingers you can access it without removing the manifold, especially if the oil filter is out of the way.

I'm sure if you look on YouTube there's a video showing exactly how to identify and access it. I'd take a photo of the one on my spare engine that's out of the car to show you, but when I tried to take the tarp off it, it was frozen to the ground.
Sigh.
