FPR problem PLEASE HELP!

[DMAN302]

Ok long story short..cleaned TB with GUNK TB cleaner with car running...left me with high idle and surge, so about $100 for new TPS sensor and IAC cause the car has 190,000 miles and I figure new is better, then still crapy idle so remove TB and clean it and EGR which was REALLY gummed up, I suspect from carbon and grease combined with liquid TB cleaner *ucken mess! Now I have done the Idle ajust and reset TPS about 3x and finally I have rock solid idle at about900RPM and I'm not touching it..BUT sometimes RPM's will hang or spike about 100-200 during shifts intermitently. And I noticed my fuel pressure gauge is stuck at 38PSI with stock regulator. When I pull of the line Pressure jumps to 39 and car Idle increases significantly to show me I don't have a leak (also checked for leaks 20HG all good vac off the vac tree) Question is...is pressure spiked because of bad regulator? it drops to 34-32 when I shut car off and hangs for ages so I think pump is ok. 2ND would spiked fuel pressure affect the rpm hanging during shifting or affect Idle?? CAR IS KILLING ME I CAN'T MOD IT IF MONEY KEEPS GOING INTO MAINTENENCE AND I DON'T WANT TO SPEND GOOD AFTER BAD IF I DON'T HAVE TO..ok done yelling now, guess my short story not short afer all

I don't know about milage yet this year but I'm at about 140 for 3/4 a tank..not bad considering all the problems with the hanging idle and city driving trying to teach the **cking computer how to idle and drop to idle properly...easier to teach my to labs not to touch the pizza when I go for a drink. I have no idea why me fuel pressure is comming up (or yours either) but I don't think its all that good for the system...I was hoping for some decent input here cause someone seems to nail the problem right on the head when ever I post on here so stay with me noslow and lets see if someone can help us out..come on guys!!

oh as for the miss you were asking about..no actuall I don't have one there but I do have a miss at idle which i think is a bad plug wire

do your injectors have 190,000 on em too? Block off your return fuel line and dead head the pump, that'll show you if the pump is weak or your regulator is.

Can you explain dead head the pump??
