So today my car decided to start acting funny.... i started it and it went from 2k to 300rpm in like no time flat and than i would hit the gas pedal and it would just backfire and so forth.... I also would be at a light and when i would start to go it would hardly move until i hit about 2k..... It bogs down and **** ton and it wont do anything but backfire and it idles really low and rufff..... Any ideas

 

I'm having similar problems, and I believe the idle issue is your IACV, and your bogging issue has to do with your spark. Today I bought a valve cover gasket(had oil on my spark plug wires), plugs, and wires. And I'm going to clean my IACV tomorrow.

I'll let you know how it goes, and if it fixed any / everything.

 

check engine light....start there.

 

having same problem, i had a misfire in all 4 of my cylinder, could be bent valves

 

well i have CEL on but its saying MAP Sensor.... Also have had this since day one i bought it though and ran great when bought..... I mean im just not sure... I hope to god it isnt bent valves, although good time for rebuild.... So i mean do you think a tune up and some cleaning could do something good

 

A full tune up with plug wires is where you start. At night start the car get it running good at idle. Pull a plug wire and look down inside the plug well with the car still running and the plug wire still in the plug well but pulled up enough for the cylinder to stop firing, see if you notice sparks jumping from the plug wires to the inside of the well walls = bad wires.

 

well know the car is being weird.... I start it in the morning and no problems.... Later in the day for some reason.... it starts doing the misfire and bog... It also doesnt get any sort of acceleration until about 3k so what the hell does that mean....

 

seafoam it before replacing spark plugs, and make sure pcv and brake booster line are tight or you will get weird results and fluctuating idle

 

Your coil may be overheating later in the day with more dirving and more underhood heat, it is easier to fire a cylinder at higher RPM since the timing is advanced more and the compression is lower, higher compression is harder to ignite.

 

so how do u fix this?!!

 

yea thats my question

 

what car u driving and what year? model? could be same problem i had with my 96 integra gsr 4d

 

i have a 92 integra ls,gs,rs... All the same motor all the b18a1 so would you know what is going on....

 

This sounds like an ignition issue. If you have a buddy with same dist. swap out the dizzys to confirm. It sounds like the ignitor,cap or rotor is actin up. No need to spend $$$$ untill you can confirm the fix. Id look into the map CEL regardless as this will cause many other issues,

 

ok so then i should check this... Ok ill try....im not sure of how many ppl here in MI have Da

 

I'm going to go with the MAP as well. It might be reading "well enough" for the most part and then spazzing sometimes. I had a similar problem when I had a loose wire on my 3 bar. The map goes blank and next thing you know you're pooring in tons of fuel and it does the sputter/backfire/bog/stall thing.

 

so it might not even be my spark or ignition or anything along those lines.... So can some one do me a favor and find me the MAP sensor and show me the link of any where it would be the cheapest.... PLease the cheapest... i dont have a **** ton of cash at the moment

 

yeah i get the same thing sometimes.
around 2k to 3k it boggs, in till i floor it..
idk wtf?
so far..
new cat
new sprak plugs
new distributor
o2 is working fine
new fuel filter
thats all that comes to mind?

i was told to try the pgm efi main relay..
has anyone tried it yet??

 

if you did all that and its still doing it, then something might be clogged somewhere or you have bent valves, time for a new head

 

naw..
it dosent happen often..
...it hasnt done it for like two weeks.. idk?

Bent valves are intermittent? Go figure
