Hey all, I have a 1992 RS w/ 305 tbi which ran fine until I hosed down the engine compartment. Had sat awhile so wanted to clean her up inside & out. I let engine idle while degreasing it & seemed fine, so I finished up & called it a day. Went out next morning and started it & now it starts up, idles then stalls out unless I give it gas. I inspected vaccuum hoses & any connectors I could get too thinking I may have bumped during cleaning. Also removed dist cap thinking moisture issue to no avail. With breather cover off I can see injectors shooting plenty of fuel until I don't press throttle to keep it running. What have I done to it? Preferred being dirty I guess? Any help would be greatly appreciated, thanks again to all and to this forum.

 

No idea if TBI has a mass air flow sensor or not, but if it does check that out.

 

Thanks zRaffz, that's on the passenger's side close to firewall correct?

 

Nobody's had this problem but me? I've been driving Chevys all my life & never had one crap out like this after detailing. '84 Z-28, 73 Nova, granted they were carbed & not tbi. Have a Ford ( 1969 F-350 Dually-hauls gas not a$$ ) and can't afford drive it everywhere, winters coming.

 

Failed to mention I replaced the fuel filter and fuel line ( from rear to front ) because the line fractured due to rusty condition while removing filter. Also replaced brakes, brake lines, altenator & serpentine belt all way before engine-stalling issue. Only after detailing engine compartment did this begin. Now it's a better lawn ornament than a Camaro.

Sorry, I intended to say I removed the dist. cap & it has no hairline fractures but all contacts are white & corroded. I cleaned them as best I could & the rotor button contact thinking it might be an issue. No difference in idle problem. Can a fuel pump go bad overnight while parked? Sorry, stupid question. Just can't get my head around this.
