91*LX*302

Hi,
First time posting here!
I have been trying to figure out a little problem that has been bothering me.
I have a 91 LX, bought it six months ago.
Here are some of the MODs from what I've firgured out have been done to the engine:
Cobra upper and lower
24lb injecters
73mm MAF
65mm Throttle Body
Under drive pulley set-up
aluminum heads-don't know specs
has a performance cam-don't know specs

Here is my question, car runs great, a little on the lean side(can smell it, butnot significant).
After about a 1/2 hour warm up, acceleration is degraded and it hesitates a lot
at lower RPM's if I give it a lot ofthrottle. I want to figure out what causes this.
I am going to buy a fuel pressure gauge and want to know if I could drive the car around with the gauge
attached to see if my fuel pressure drops after the car warms up, is this somthing that i could do
without any problems? I believe, if the fuel pressure drops, I willbuy a new fuel pump.
I changed the inlinefilter already. I also thought in the beggining that it could be timing, is that possible?[/blockquote]

I would check the timing first thing that would not take long, then the gauge would be next.

if timing hasn't moved it is unlikely that is the prob unless excessive chain stretch has occured in that case no adjustment will fix that.....first I'd run a koer test and look for codes after that check tune up parts and clean maf sensor with maf cleaner

oh and yes you can drive around with a fuel pressure gauge taped to windshield to monitor any pressure drop...done it tons of times
