I recently went from a double pumper to the new DW300. Went in to get tuned, wasnt getting enough fuel at redline at only 400whp on e85. Tuner suggested i might of had a leak at the fuel pump, so i got new seals from DW and put that in. At the same time i switch my ets intake to aem for carb reasons. that all i changed, car was running perfectly fine for several weekends. anyways after that My car won't idle at cold start, i hold the gas and let the car warm up and then it'll idle buts its rough.

Could it be that it was leaking bad enough to throw off my fuel map? or is something clogged. I'm running rc1200cc for about 2yrs only on e85. I've been reading all the idle thread. Can anyone give me some troubleshooting procedure if im doing things right. I tried unplugging the IAC and it idles about the same, is the car suppose to die if i idle with the MAF unplug? and do i unplug these things while the car is idling or before i start it up?

What should i use to clean the IAC and TB?

 

Did you do a boost leak test?

Sounds like maybe you have a coupler leak after the MAF possibly.

 

nvm...hahaha...i was on my 91 map, been on e85 too long, forgot i had to change it back after unplugging the battery =)

 

^ I do the same thing everytime the battery gets disconnected!
