My 2001 4.3's are not been behaving.
Initially my port engine kept dying and would not restart. I replaced the anti-siphon valve as it looked very corroded. Good to have it replaced, but didn't fix symptoms. I then swapped IAC from starbord to port and motor started. Starbord would not start with the port side IAC in it.
Yesterday I received the new IAC's in the mail and replaced both. Both engine startup fine now and the starboard is running strong. However, the port side still isn't perfect. When I put the motor in gear and push the accelerator
down it will climb to about 1500-1800 and start bogging down until it max out at 2100 and have fuel fumes coming out. If I slowly move it forward it will build up RPM and have power. Basically it boggs down with any really acceleration unless it is really slow and deliberate.
I watched the injectors running both motors and no noticable differences.
I am thinking the next step should be replacing either the TPS or shift interruptor switch. I am going back down to the boat tomorrow and will try swapping these parts from the starbord to the port.
Are there any other ideas?:huh:
Thanks
