So I start up today and start going and realize for some reason my vtec wasn't engaging. I got into VTEC range and all I would get was a HUGE backfire. Well I reset the ECU just to see if it was a bug. Well it worked, now however, whenever I turn w/ some acceleration the car basically loses power about halfway through, backfires and then gets going again.


Any clue anyone?

This one definately has me stumped.



Keep in mind, I have a 99 3.0

 

how many miles on your bitch now?

 

almost 80K. Car has been pretty well taken care of, do all maintnence, etc.

 

A friend and I are thinking it could be the fuel pump

 

Throttle body, map sensor is my guess. Was a common problem on gsr integras

 

but wouldn't it shut down at WOT in a straight line also?

 

BTW, i have no check lights. Only mods on the car currently are CAI, Greddy Exhaust, AEM Pulleys. Haven't squeezed a bottle through it in a little over a year.

 

Are you low on motor oil?

 

when you say "basically shuts down" do you mean the engine basically DIES for 1 or 2 seconds then it kicks back up?

 

take it to AutoZone and get them to do one of those ECU scans to see if youre throwing a code. those are usually pretty effective at diagnosing an array of engine probs, especially if its got to do with your O(2) sensor. possibly a vtec solenoid

 

Stop hiding your dope in the gas tank, bish.

 

Nope, checked that also

 

yea, if it still does it tomorrow i'll go over to my buddies and we'll check to see if it's throwing a code. But it's not otherwise the check engine light would come on.

 

still, lights fuck up a lot too. i mean hell, if your car is having heart attacks and VTEC isnt kicking in its obvious you need to CHECK your ENGINE. who cares about the check engine light haha.

 

My civic did a similar thing and I found that one of the plug wires was no longer seated correctly. It wouldn't VTEC and it basically ran like shit, but intermtitently. You might check all the plug wires to be sure.

 

good call, that is one thing I didn't check!

 

Okay, I went and checked the oil again and have virtually none in there

I'm thinking I may of cracked the pan this weekend.

 

bad bottom out or something?

 

Low on oil and the light didn't come on? Ummm...better check that out too. As for the VTEC, check the VTEC solenoid. It happened to my civic before. I had a loose cable connecting to it.

 

is the car completely warmed up ???

thats the only thing i can think of
