bad idle and stumbling throttle

[SpoCom]

I have a Ka24de that has been rebuilt nd swapped frm auto 2 manual. When I 1st bought it the car ran fine now I've got an issue or 2. When I get n 2 start the car it doesn't even turn over the battery light comes on nd the MIL blinks on/off a few times. After turning the key all the way off nd tryna again the car will start but immediately fall to a very low rpm sometimes even die. If the car doesn't die it shakes almost violently as I idle below 1k. I rev it a bit nd the car then idles around 1k then maybe goes to 1200 rpm but falls again. As I drive whenever I am on the throttle the car stumbles hard so hard sometimes the entire car is jerking nd when I stop @ lights it continues to idle poorly. Meanwhile all this is going on the MIL is off but the battery light remains on.
Any advice??

easiest things wuld b...check the voltage on the battery...do a load test (turn all lights on and put in hi-beam, turn ac to high) thats if u can get it started. thatll tell u if the battery is good or not. next wuld b to chek ur grounds. alota these problems come from poor ground. make sure all connections are clean and metal to metal. make sure everything is connected. thats all i can giv u off the top of my head. gluck nd keep us posted.

I.did getta battery test yesterday nd its good as far as grounds my alternator was puttin out 51A when it should be 80 nd the neg terminal has been cracked almost into 2 but is still on snug tight. The way the guy had it b4 has is alil different nd Ima have 2 get creative wit switchin it out . Wut I noticed also juss last nite was my temp gauge RITE below the H I cnt do no more than 25 . My friend had a similiar problem wit an EG hatch said it was his head gasket so 2day ima order the gasket nd lata this week I'm gettin a new alternator
Ill keep ya posted

you might have some nasty vacuum leaks
clean the terminals on the battery and as for the terminal being cracked do you mean the metal post that sticks out is cracked, is the plastic of the battery cracked, or is the clamp that attaches to the terminal is broken? either way get that fixed asap, make sure your alt bet is good and snug before you replace it, if that doesnt help replace the alt.
If that doesnt help any of your problems do a compression test

The problem is fixed. After runnin codes off the ecu I found a bad coolant temp sensor bought a new container 4 my coolant nd relocated that 2 the otha side of the motor. That solved the overheatin problem. Then I did a tune up nd wut was makin it idle nd run rough were very bad ignition wires. I took noticed of my distributor cap havin only 1 screw reason being the otha screws threads r still n the hole 4 now it isn't affecting the car but I kno that must be fixed soon. As far as the battery terminal being cracked its the metal part that wraps around the post itself attached to the battery I do believe the battery lite is on when I drive hopefully when that gets fixed it'll come off.

Ty 4 the support nd suggestions

no prob man. thats what we're here for. i suggest gettin new battery clamps since they are pretty cheap. good to kno that u solved most of the problems. prolly shuldve pulled the codes first tho haha. jus a friendly suggestion. hey, how much were ur wires? and what brand? thanks

Hey shimi I come on here thru my phone so I juss checked the post srry 4 gettin back so late. I actually came back on bc juss last week my car began missin again and my bebe was doin more than idlin rough the car was actually dyin @ red lights nd stop signs it was missin so bad. The stumblin stopped but the miss was back. Popped the hood nd 1 of my wires was slidin out a bit so I decided 2 pull em all I 4got the namebrand but they were thee most horrible wires evr bc the 2nd wires snapped n hlf nd the 3rd nd 4th wires' handles came off those 2 were removed wit pliers. Those wires also had rubber boots @ the bottom as I pulled the 4th out the boot got caught comin up I went 2 use a flat head 2 get it out nd it fell WAY 2 the bottom. So I then had 2 take off the valve cover juss 2 be able 2 see nd have more room 4 the screwdriver. When I went 2 take off the cover that's when I saw THE ACTUALLY PROBLEM. The rubber boot frm the 1st set of wires was still n the hole so when new wire went in it wasn't catchin the plug. Afta a day off stabbin @ those boots wit juss a flathead I finally got them both out. Bein that I snapped the 3rd wire n hlf I needed new 1s. 1st time I went 2 the parts store I was given wires wit the boots already glued 2 the wire itself but there were only 4. When I changed em @ the store I was given "OMNI" wires those r designed where there isn't even a booot its juss the wires nd a very strong handle 4 pullin.I also bought new plugs the old 1s were PITCH BLACK @ the tips build up was insane. I got NGK platinum
