Purchased an 88 TC about a month ago and have had a few issues. I'll start off by telling you what i've done.
Set base timing and idle.
Set TPS
Cleaned IAC
Fixed and verified vacuum routing(thanx to this site)
Fixed tear in egr diaphragm(holds vacuum now and no more code)
Checked Fuel pressure(32psi at idle with vacuum, 41 without vacuum). Now the wierd thing i noticed yesterday. Starts at the 32 psi idling when cold. After 15 min of running it was up to 38psi. Have not checked pressure while driving.
What I'm getting is a very slight rough idle(was worse when egr was hooked up wrong) and at cruising rpm around 2200-3000(doesn't matter what speed)I'm getting what feels like a miss. And if i'm trying to enjoy some "spirited driving" between 3500-4000 its starts to buck and fall on its face. Like its running lean or the timing is being backed off.(knock sensor not hooked up).
It appears that the WG is either blocked shut or is stuck shut(can't even move it by hand). Has a BOV wich seems to work fine except for one time the otherday when i was getting on it the intercooler was blown off the throttle body when shifting at roughly 4k rpm. Though I think this was a case of the clamps not being on all the way or tight.
Sorry for the long winded post, just getting frustrated with it. I don't really have any driveability issues while driving normal and im still getting between 22-28 mpg depending on how bad of day I had at work
Thanx for any info or help you may be able to give.
