So heres the deal ---- I've read through pages and pages of forums and have found no luck w/ similiar problems . Here are the details -
1996 Civic EX 1.6L vtec
I Took a motor out of a 1998 Civic DX 1.6 non- vtec and used the short block(the lower end).
I took the cylinder head off of the 1996 vtec engine (d16y8) reworked at machine shop and mated to the the lower end of the (d16y7).Replaced Plugs,oil,coolant,valve guide seals,etc.
Only difference I found in conversions where the intake manifold,exhaust manifold . Vehicle will not idle at low rpm's and throws a couple of CEL codes-
p1300 random cylinder misfire
p1508 idle air control valve malfunction
p301 misfire#1
P304 misfire#4
I reset the CEL , cleaned IACV valve (IACV worked fine on old engine)have adjusted throttle cable to get it to idle . But as soon as I accelerate to 3,000 rpms or higher and let off the gas it dies out . When starting the vehicle it seems like the camshaft is spinning faster than normal almost as if the belt is loose or snapped . Have rechecked belt /TDC but probable a starting point .
I'm looking for suggestions or just flat out help - - Not too familiar w/Honda's . I havent checked the compression yet ,TDC,or swapped to d16y7 ecu .
I'm stumped !!!! Just looking for flat out suggestions while I wait for this storm to pass....All help is appreciated
