But I wouldn't jump ship just yet, try some of the solutions offered. I'm no tuner but something is telling you that your not running optimal A/F ratio. Just swapping out the intake, I highly doubt, will solve your issues. I'd at least try the below solution: Quote:

lol yeah I was merely jesting. I mean, yeah you'd get power haha, but I know most people don't want to dump 33% of the cost of the car into a supercharger.

It gets 100+ with 60-80% humidity around here :P I sortof doubt it gets that hot up there.
I just use whatever thermostat came in the car and it works fine with boost and all the other junk I've got.

Of the areas where there could be a leak (below) they all seemed fine. -Intake manifold to Head = check -Throttle body to Intake manifold = check -Intake piping = check -Brake booster vacuum line = check (factory line) -Evap system vacuum line = check (factory line) -CrankCase vacuum line = check (exact specs as factory, only 1 inch longer) -CrankCase fresh air line = check (breather) -Exhaust Manifold to Head = Check -Exhaust Manifold to downpipe = Check -O2 sensor = check I might start with just swapping back the OEM TB (Like many have suggested) and go from there................ |

not to go too far off topic............. Its funny that people think of Canada as the land of Igloos. here in Ottawa (capital of all Igloos) its currently 78 F which is unusually cool for this time of year. All through July we were mostly in the 90's, with many days in the 100+ range. Admittedly our Winters are colder, but our summers are the 60deg F that people imagine they might be. |

You would be surprised at how a thermostat can put a car out of whack... This past weekend I helped my neighbor install a thermostat in his work van. It failed emissions, when he got the ECU scanned by a GM tech it was stuck in open loop mode, and would not get above 150f - which is about the temp of that unit you put it. In his case when he had the radiator replaced a few months back some knuckle head cut the core out of the thermostat (no idea why, could have been stuck), we put a new stock one in and now it passes smog.
I run a cooler unit, because we run a 30-40 min race and spin over 7000rpm, but I have complete control of my fuel via my AEM ecu. On a road going car with a stock ECU you have done nothing but fatten up the mixture. No upside.

I do whatever satisfies the customer.
It's no problem for me to simply bead blast it again and sell it to someone else. I know that there's nothing wrong with the manifold because I've been running a tooter for over a year and 6,000 miles and it works great. Jason mentioned the low temp thermostat, and I agree. I'd try removing that first because my guess is that it's screwing up the ECU which stays in "choke" rich mixture mode constantly waiting for the engine to warm up. |

Every few years or so, we get a day where we hit 120f with humidex, but that's rare.
Usually we'll get 5-10 days of 110f temps with humidex every summer. 3 weeks ago or so we had 5 days straight of 113f with humidity, it was nasty outside. OP, as for the issue at hand, the main question is, when did the problem actually start happening? Or did you do all the mods at the same time?

That and the TB swap are the easiest. When I get some time this weekend I'll first try the TB and then the Thermostat. Will |

In actuality here were the problems I encountered: -ARP exhaust manifold/head studs wouldn't install in the two outer locations (where the factory studs were (so right now for the DC Header I'm running the inner 3 head studs from ARP and the outer two head studs are factory) -The Red Silicone rad hose from the head to the rad cap housing,..... doesn't fit the housing (its too big around) ( I notice in other peoples install pics they aren't running that hose and it makes sense why) -The DC Sports header debacle with the O2 sensor bung being too close to one of the downpipe bolts -The "Odyssey" battery (Sears Diehard Platinum) although a "standard" 35 size is actually marginally taller than the factory battery and therefore is a VERY tight squeeze for both the factory battery bracket and clearance to the Ultra Racing strut brace. -I also had to fabricate my own Crankcase vacuum line because the Intake manifold side wouldn't fit the Tooter nipple(too small) (although the nipple for the EVAP vacuum and the Brake booster, both fit perfectly) then of course I also forgot to re-connect the wiper motor so I had to tear the cowl off a second time to re-connect the plug.

Based on Jason's expertise, I would do the thermostat first. As a quick and dirty test today, drive it and see if the green coolant light goes off. If it stays on and green, then you are in "cold start" mode. If it goes out, then the thermostat is likely not the issue.

That cold mode does a lot of weird things to the motor. I made a video a while back about how my boost behaves differently when the engine is cold.
