Hi guys,
I thought I had solved my first start problems last fall when I had the my swap done, by cleaning out the Idle control valve. But it has return with the warm weather. Here is my problem: All winter, car starts fine with no problem at all. Now with the warm weather (above 65 degrees), when I first start the car it will start (at a low rpm 500) and slowly within a matter of 3secs stall. But if I start it up right away, it will start and run fine as if nothing is wrong. This seems to be happening with warm weather and the other thing is it ALWAYS ALWAYS starts fine on the second attempt, ALWAYS. I never have to start it more than twice. Also on first start ups when it is about to stall, if I lightly tap the gas pedal and let go, it will continue to start and run without stalling on me. I read the cold start problem thread and now I'm wondering if my problem is the CSI or the coolant tempt sensor or something related to fuel? I have cleaned out my throttle body and the Idle control valve but to no avail. Any help will be greatly appreciated. Thanks This post has been edited by malecrod: Apr 28, 2007 - 12:14 PM -------------------- 3sgteing.

If I were you, Id clean the throttle plate. If that doesnt fix it price a IAC at toyota. Or get a used one |

Well, I cleaned out the IAC again last weekend. It wasn't as dirty- at least not as before. But I was in Chicago this past week and picked up 2 CSI from 5th gen celicas in a junkyard with numbers ....#20020 and #20030. I put the 20030 in this evening and it fires up fine. I will let you know if this solves the problem. Thanks.

Yeah, Lagos, I think it is the cold start time switch because the car started a lot better than before (kinda like how a car SHOULD start). So I'm almost sure that was my problem. I called toyota up for pricing and it was $158..Arrghhh lol. So I went to the junkyard and got 2 for $10. Thanks Lagos, toyotacrazy and everyone for helping solve post swap bugs one at a time. -------------------- 3sgteing.

I'm glad to announce that the starting problem has definitely been solved.
Now, I have another question to ask: I have a FMIC set up and I just noticed a few days ago when it was warm outside that I couldn't boost pass 8psi. But today at 49degrees outside I boosted to 11psi. My question is, is this 1.NORMAL, 2.poor intercooling problem, 3.low octane gas, or combination of #2 and 3. I currently could only buy 91octane gas where I live. Also if I change my intercooling piping to go around the heat shield like Tufy's set up would that help? Any advice would be greatly appreciated. Thanks -------------------- 3sgteing.
