Hey guys, I need some direction here I don't really know what to look at on this one. Having an issue where once the car is fully warmed up (driven for about 20-30 minutes to where the oil pressure drops down at idle) it will start stalling out at cruise and idle. Its seems like a power loss issue not so much a "miss" the check engine light comes on and the engine goes silent for a bit, then it starts firing again CEL turns off. this occurs a couple times per second and happens in spurts where it will do this for about 30 seconds and then it will stop. if I let off the gas the CEL will flicker and the engine stumbles really bad. once this starts happening it idles rough and dies every few seconds as well. what I dont get is that the car runs flawless when it cold, idles awesome runs smooth all the way through the rpm range. this has happened the last three times i've driven it now. everything starts out great then once its warm the stalling starts.
I've checked all the engine grounds are tight as well as the one on the coilpack, pulled the conduit off didnt find any broken or shorted wires. change some vacuum line(not really related was already planning to)
scanmaster at idle when its running ok
int 140
af 6
l8 27
ats 160
iac 28
cc slowly climbing (takes about 30 seconds to get to 250 and reset)
tps .40
when its stalling at idle I did notice the tps will flash to 0.0, other numbers do fluctuate aswell but the engine is also struggling to idle.
I think I 'll try to get ahold of bob bailey tommorow and ask if this has come up as an issue with the TR6 ign. other than that im not sure where to look? coilpack, o2 sensor, cam or crank sensor?
any advice or insight would help if you've got it. thanks in advance
