I have changed the dizzy cap an its still near stalling an it doesnt have any lights on the dash its when u accelerat it splitters an splatters an nearly stalls

Hi Madw.

If there are no engine codes test the vacuum system and try replacing the sensors in the air intake.

Small vacuum leaks often do not trigger the check engine light. Bigger leaks can be detected listening to the hissing noise. Smaller leaks are detected using an hand tool gauge in the vacuum lines while heating the lines at same time. If pressure goes up while heating vacuum lines, then there is a leak.Here a gauge:Actron Vacuum Gauge, Fuel Tester.
Using the same gauge you can check pressure in lines from tank to fuel pump, and on fuel pump outlet. Althought a faulty fuel pump will trigger a misfire code, better checking fuel pressure while the problem occurrs.

Check the MAF and AIT sensors. This sensors located on the air intake determine the amount of air used in the fuel mixture. Bigger faults are detected with lean or rich mixture codes triggered from O2 sensors, but smaller faults goes undetected and can still cause the engine stalling or behaving erratically.

If car is revving up and down and stalling even while driving , check the EGR valve. This valve opens and close to add recirculated gas from vacuum to the fuel mixture. Here an article illustrating testing procedure:EGR Valve Problems.
