Let's start from the top Posted by Ari [Email] (#2847) [Profile/Gallery] (more from Ari) on Thu, 10 Feb 2005 20:02:27 In Reply to: Re: This thread continues to amaze and confuse, vince v, Thu, 10 Feb 2005 13:55:35 Members do not see ads below this line. - Help Keep This Site Online - Signup |
OK, it's a 91 N/A with DI. Hard starting when warm. You can read codes - what codes do you read? Is there a Check Engine light?
The other thing to check is the Throttle position switch on the throttle body. If the car thinks the throttle is wide open during starting, the ECU cuts way back on fuel. I'm wondering if the TPS might have an open circuit when warm. That could cause a hard start issue. Pull the connector off the TPS - measure resistance between pins 1 and 3. It should be 1.1K to 1.5K at Wide Open Throttle. It should be 2.6K-3K at idle position. I'd try measuring it when the car is warm, and again cold. Just a thought.
What codes? A CEL?
