Replaced coil packs,icm,fuel pump,filter.Whenever the engine is under load it bogs bad.When you mat it it wont rev past 2grand.If you feather the gas it will cath up.I pulled the mass air off while it was running it seamed much better.Of coarse I got a code for this.I do get a lean code also when the meter is hooked up.The meter checks out ok.I'm thinking bad injectors?HELP!

I had a similar problem with my 1990 2.3L when i owned it. It took forever to rev and had no power at all.
The timing belt had ended up jumping a tooth on me.

Its best to just get a new crank sensor, there kinda hard to test. But I would defanatly check your cam timing agian, ive done that before and that is exactly what happens, just wont rev up. Try gettting a new timing belt and going to Stingers site and read how to set the timing corectly http://stinger-performance.com/tech.html and setting the timing agian. Hope all turns out well.

sounds like the Mass Air Meter.
Mine was doing the same thing, it will throw all sorts of ugly codes because it throws off everythign else by tellign the engine the wrong amount of air is going in, resulting in too rich or too lean and then you get anything from O2 sonsor to knocking, and bad stalling.
Picked up a rebuilt unit and put it on, drove it home and have had no problems since.
First I thought it was the EGR valve as it seemed similar to a problem I had on a different vehicle. So I put a (very expensive) egr valve on it only to have it do the same thing as soon as I started driving it after.

Well, I unplugged the connection that goes into the MAF, the connections seemed okay but there was white stuff on them...wiped them off with a paper towel, hooked it back up, and still have the same problems. Oh well. I didn't take the box off, just unplugged the connection. Not sure if there's something else I should do, rather than what I did (I'm sure there is), or if I need to take that box off and disassemble it further.
I haven't been able to check the volts - we have one of those testers, I just have no idea how to use it, and it's hooked up to my Dad's '66 Mustang right now... So I'll wait until 4pm to try that.
I'm such a newbie to this gearhead stuff. It's fun but confusing, haha.

try unplugging it while it's runnig to see if it changes.
I have almost the same problem. I unplugged it while it was running and the engine started and ran fine. I replace with a new unit and the car starts acting up again. kinda bugs me cause that thing was not cheap.
