Engine Performance problem
1990 Plymouth Laser 4 cyl Front Wheel Drive Manual
this vehicle will not rev up, it boggs and cuts out as soon as turbo spools up. It has fuel pressure (38psi), new pump and filter. all four plugs were fuel fouled. 150psi compression in all cylinders. tried new plugs, wires, coil and ignition module. no air leaks found after maf to throttle body. tried used crank angle sensor and known good maf. nothing fixed the problem. timing marks on cams and crank line up and timing is set at 5 degrees. vehicle runs ok until turbo spools up. exhaust is cut at downpipe to eliminate plugged cat. any help or advice would be appreciated.
