Kind of bad misfire and idle problem

[milby43]

Hey, ive looked everywhere, and still couldnt find anything. Trust me im not one to just slerp information with out trying to find it myself.

So this is whats up.
Once it warms up and the idles drops to about normal, 750-800 rpm. if i even tap the throttle to rev it, itll bog a little.
Then when you let off the throttle, itll drop to 500rpm then go back up to 750-800rpm

Now I have a misfire, and I dont know which cylinder it is, or how to find out. The only way i know is to pull off the plugs when the car is running. But that can mess up the coil pack, and if it aint broke, i dont want to break it. Cause im kind of out of cash right now.

Any ideas? Theres a new air filter, the plugs look new but im gonna get new spark plugs (any suggestions?), i heard not platinum.

I have a throttle body shaft seal leak, but my vacuum is good.
The honey comb on the upper comb of the mass air is a little damaged.

It doesnt smoke, and im pretty sure it doesnt smoke on start up, heres a link to a walk around, and start up.

ANY advice or tips would be greatly appreciated , its not legal yet, so i cant drive it around. If the problem still persists when its legal, im gonna get some good fuel system cleaner and hope it works.

Thanks alot
Andrew

1. Check you MAF, make sure it is good.
2. Try unplugging the vacuum hose to the FPR when its running and see what happens

Test your coil pack, plugs and wires. Obviously, you "slerp information because there was the same problem earlier, search the site please.

Trust me i have, i try to learn on my own first. But dont believe, its what ever.

Im check the coil pack, plugs and wire today.

Check MAF? like see if all the plugs are in and such? Cause the only think i know is wrong with it is the little spot of bent honey comb

If you have a Haynes or Chilton book it will be in there

ok so i tried removing the vacuum from the FPR. no luck.

im gonna check the gaps on the plugs

 

[Usatuff]

OK, I'll get you instructions for the MAF test too

also switch to regular NGK plugs NGK SPARK PLUGS | BPR9ES | BPR8ES | BPR7ES

alright ill get them tomorrow, what should the gap be, i have a gap tool that has .030 and .025. I think its suppose to be .028 right.

 

[Usatuff]

what psi are you running at?

 

[milby43]

im running stock boost at the moment.

also regapped the the plugs. Still no luck.
Im getting new plugs and wires, then if that doesnt work a new coil pack

Check your maf, check for vacuum leaks and check for boost leaks
