I had a bad oil leak out of the main crank seal and im lazy so i took my car to honda (dad's paying for bday present)...anywyas they got the car mechanically back together...but they called me and told me that the engine surges when they start it up...

Can anybody think of anything that would cause that to happen?

 

oh yea, 98 civic HX body 00' d16y8 in it.

 

Call Tuners Edge, It is a conflict in your wiring harness. I have an LS in my hatch...did the same thing as yours. Took it to them, and turns out it was a conflict in the wiring harness. They know their stuff...Props for Tuners!

 

common sense says it is a conflict somewhere within the electrical setup of the car... dont go pay tuners edge to do something that you can do yourself until you know you cant

does your car utilize an idle air control valve? is it throwing any codes? tell them to hook the bitch up to a scanner and tell you what it says. what all was done when they removed the crank seal? im guessin they yanked the motor out of the car?

 

check th IAC. could have been damaged while being worked on. that happened to me. check the pcv valve, or just buy one and put it in, its only a couple bucks. check all vaccuum lines, one couldve gotten damaged. oh yea, and make sure the wiring harness for the IAC is plugged in, the last time i took my IM off i forgot to plug it back in.

 

If want help just hit me up.

 

Just because one car had an issue does not necessarily mean they all will have the same issue when a similar problem occurs. I am with Nick on this, check the IAC valve if it has one. Check all lines and vacuum hoses.

 

im gunna poke around at it but quite frankly i dotn konw what im doing...

It only idle surges sometimes...like itll just go away at random.

I'll probably end up taking it to tuners edge....hatch77 how much did it cost u to take it there?

 

And turns out there isn't a plug on my wiring harness for my post/cat 02 sensor...wtf???

 

if not the iac, try a throttle position sensor.
