1989 Chevy K1500 350 tbi auto trans A/C and just did an engine
swap with a motor from the same year vehicle. Running VERY rich at start up and have exhausted my knowledge on how to solve the problem. Replaced CTS with a new one. Checked yellow wire to CTS to verify current at 5.43 volts. Checked IAC yesterday and it appears to be good. Any suggestions?
JA: Sometimes things that you think will be really complicated end up being easy to fix with Chevy. The Chevy Mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?
Customer: Yes, I'd like to find the answer and take care of it ASAP so I can get my old work truck back on the road.
JA: Great! What have you tried so far?
Customer: Did you read my first post?
JA: Is there anything else the Chevy Mechanic should be aware of about your Chevy?
Customer: It was running perfectly fine just an old tired worn out engine. Replaced the engine and it's running VERY rich.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Chevy Mechanic about your situation and then connect you two.
