92 coupe running problem help asap

[Bentleyness]

ok got a 92 coupe some of u may seen my post with engine problems but turned out flywheel bolts came loose So I pulled the motor and trans did some work like replace oil pan gaskets,a/c removal (because I don't like a/c, get me dizzy on all cars and trucks) intake gaskets, emission removal while I was at it,

So I have a problem and a question for nico, and I have looked but can't find anything usefull.


History:when motor and trans was pulled this was my first time btw I labeled all lines and wires so it was plug and play when it was time to put together, replaces gasket where needed, emission. Remove, motor put back in

Problem: after a day of good running it now doesnt wanna past 2500k rpm in all gears and car eats poop amount of gas like 1/4 tank for a 15mile trip! Car wants to die at idle and when at a light so I have to bump the gas around 1500k, if not it revs from 500 to 1200k rpm. I also figured car is running rich cuz I smell gas, so right now I'm lost and need it fixed,


Question: I did egr remove and all thoses mazes of lines in back of motor near the firewall so all there's left was the the fpr, scv and egr was blocked off.

So the nipple near the brake booster is hooked up to the fpr and the scv For vacuum is this right?

That almost sounds like the O2 isn't hooked up or is bad. If its not hooked up the computer goes to a default mode that doesn't allow you to rev very high and you get crap milage. Just a guess on my part but maybe it'll lead you in the right direction.

It sounds like your MAF is in saftey mode. It happened to me before and it would not rev past 2500 and it wouldnt hold an idle at all. Check your MAF connector mine was really dirty and it came loose.

found a vacuum leak on the brake booster line fixed it and maf was loose so got it back in but idle is still jumping and sound like its going to die.

and the o2 sensor i found was unpluged for idk how long when i bought the car and was to busy with work at the time so never looked under the hood but car ran fine? as of now it is pluged in but still not as bad as before, i can rev it to 3k so its not limiting my rpms

but the question about the emission remove still bothers me car ran super good befor i took it out so just wanted to make sure its right'

vacuum line from lower intake to fpr right?

a/c removal (because I don't like a/c, get me dizzy on all cars and trucks) intake gaskets, emission removal while I was at it,

your car is running like my single cam was running....I never figured out the problem and ended up building a new motor.

check your throttle body, get some TB cleaner and spray it down and then wipe it clean and try it, it should help your idle issue, it helped mine
