I purchased a modified 98 dc2 from my friend and i have put it back to standard but have a few issues.
The car starts and runs. Bit the idle when warm is around 1250-1500 ticking over and when pulling away and coasting etc the idle can climb to 2.5k and hang around there.
The car had an aftermarket TB. I replaced the TB and IACV with second hand items.
So far i have
Checked the TPS values and adjusted it
Cleaned out the IACV and checked resistance
Blocked all vacuum pipes to check for leaks
Sprayed brake cleaner to try find a vacuum leak
Adjusted throttle stop and clean TB to get best seal
Screw the idle screw in as far as possible to see if idle drops
My next options are, try a 3rd IACV or replace the second hand throttle body. I think the idle screw has been replaced in it and might not give a perfect seal.
Is there anything obvious im missing?
Tomorrow ill block of the iacv port again and see if it dies and try narrow down the air supply thats keeping her revving.
Unless there is a vacuum leak. Surely its an IACV problem? Or the idle screw thats been replaced is not correct
