This is probably a newbie post, but I'm having som problems with my rpm. It bounces from 1k to 2k, then somtimes goes down to about 200rpm. Does anyone have any suggestions?

I've got a 95 honda civic with a 1.6 sohc vtec
greddy turbo kit
some kind of fmic from ebay
apc spark plug wires.

I had some work done to the bottom end to handle more boost. I've just recently got it back from the shop it took them about a month. When i got the car back it was fine for about 100 miles, thats when the rpm started acting up. Could it be the ignition coil or the distributor? or the crappy apc wires?

 

erm this is the 4th post of this same problem this week , use the search button and look them up. if you still need help just bump the thread

 

take it back to the shop, is it throwing any codes, maybe a vacuum leak, what work did they do to the bottom end? does it only idel wierd when its cold or warm operating temp or both? have u checkyour IACV and cleaned it.

I took it back to the shop, they told me it was the tps and adjusted it for me but it still did the same thing and they also checked the IACV for me and said it was clean. it idles only at warm operating temp. The work i had done was getting putting forged pistons and eagle rods and rings, also the block was posted. When they had the motor out i told them to put on some dsm injectors my friend gave me with a resistor box. With the dsm injectors on th4e car would not run b/c it was running too rich. So the took out the dsm injectors and install injectors from a 1990 civic. What else could be the problem?

 

u need a afc to lean out the 440s and maybe there is a vacuum leak, check all vaccum lines, also there could be air trapped in the coolant, bleed the coolant and make sure no air bubbles.

 

I'll try it,
Thanks for the advice.
