2.3 stroker runs rough at start
I would appreciate any information-thx.
I have a 95' Eclipse with a 2.3 stroker motor and a GM MAF setup... Why is it everytime i start the car, I HAVE to hold the throttle down for like 2 min. before it can idle without manually giving it gas with the throttle? Isnt there a way to fix that? SHould i ditch the GM MAF and do something else? Something must be telling the ECU some incorrect Info?

Have you tried to play with the idol at all?

Re: 2.3 stroker runs rough at start
yeah. the idle screw is in all the way.... and the idle on the ecu is set at like 1900rpms.... i had it more to see what would happen... and nothing unless i need to screw with the maf setings?

Re: 2.3 stroker runs rough at start
do you have the GM MAFT dialed in correctly? what tuning program are you running? i know the GM MAFT is a BEAR to dial in correctly, and its sencitive to every aspect, IIRC this includes hightened displacement...

Re: 2.3 stroker runs rough at start
I'm using DSMLink. yesterday i placed the rpm idle to 1200, but it kind of jumps around with the cams in it. i adjusted the variable timing a little on the high end, advancing it to make it a little richer and also adjusted the fuel settings a little. it seemed to do a little better as far as how it idles. as far as the MAF settings go.... i think i got everything pretty good.. but i could be wrong... also. what is everyone else using for synthetic oil weight for their 2.3 strokers?

Re: 2.3 stroker runs rough at start
I always use 10w-40 and plan to in my stroker soon.
As far as the MAFT with DSMLink, I understood that you zero out the MAFT and make all changes within DSMLink.

Re: 2.3 stroker runs rough at start
I run a blow-through GM MAF and have the same cold-start issue. I'm running a compensated EEPROM chip, but no settings change has ironed it out thus far.
