I've got a 1996 jeep grand Cherokee with the 5.2 v8 fuel injected Holley throttle body. My problem is while driving at soft or low acceleration it accelerates fine, but if you hit the throttle hard it

I would check the voltage on the throttle portion sensor with the engine off from idle to wide open throttle.If there are any dead spots, replace the sensor. If the tps checks out, you should check fuel pressure. If you have good fuel pressure, you may want to make sure there isn't a lot of slack in your timing chain. I don't believe you mentioned the mileage of your vehicle. Best of luck.

I have a 1990 Ford F-150 5.0 with a no start issue. I have spark, fuel,and air. fuel pressue 40 psi, good compression. I had to replace the tps.

Check that the TPS was installed correctly. If not, she won't start. You have to align it with the slot in the throttle-body housing and turn it slightly to seat it onto the hole correctly.

How do I set the timing on 1990 ford taurus, fuel pump is putting out 40 psi with engine off, key on and i put new filter on, and the car is getting spark all the way to the spark plugs, my next best guess...

first... while you have 40psi engine off do you have good flow? should get more than 1/s liter in 30 seconds

additionally, are the injectors pulsing?

finally, what is the cranking speed and is it smooth?

keep us updated

1997 Ford windstar Low power and very poor acceleration under load. Bogs down severly under load. No codes, fuel pressure at 35 at idle and around 40 under a load.

35 is low fuel pressure, should be around 40-44 PSI and 46-50 PSI under a load, replace the fuel filter it may be clogged.
