Hi geekinavette, Following the last post... I wanted to remove any doubts with respect to a vacuum leak from the toplid, I had the gaskets on hand and decided to replace the gasket. At the same time re-verified the throttle bodies and they already have bushings in them (I guess the last owner...

Hi geekinavette, Ok, I'll check for a vacuum leak once again.... Joey

Hi geekinavette, Sorry for the delay... There's 151k miles on this engine. I've checked for vacuum leaks around the engine bay and have found nothing. I did the propane and squirting carb fluid all over the place and no leak. I also did the same test around the throttle shafts and nothing...

Hi geekinavette, Removed both IAC's and cleaned each pintle and pintle seat... not very dirty as it was cleaned not long ago. Verified the pintle distance and they were both under 1&1/8 of an inch. Checked the throttle shaft for play and there isn't any. I also double checked the injectors...

Hi geekinavette, No check engine light... After replacing the ECM, started the engine and let it come up to normal operating temperature. It felt good and it was idling a little higher than normal at 1100 rpm. I then unplugged the IAC's as well as the EST , plugged up the min air passages...

Hi geekinavette, I finally installed a new ECM since the FSM was continuously pointing towards its replacement. I then verified the MAP, CTS and TPS grounds as you suggested..... with good results, continuity on each circuit. I started the vehicle and finally a much smoother idle (although a...

Hi geekinavette, I'm really scratching my head on this one... I've checked and re-checked the FSM as well as researched the issue for many hours on the net and the result is always the same, Pin 11 (from the black connector) does not terminate at any ground location ... It starts at the ECM...

Yes, I did verify the ground points... behind the cylinder head (on the drivers side) the one on the transmission housing and it all checks out. The FSM doesn't really specify where those two pins are grounded to.... I'll continue searching the fsm as well, maybe I missed something. thanks joey

Hi geekinavette, Ok, The ground point that I use is the negative side of the battery. I thought this was the best place... Should I splice into those ground wires from the ECM connectors and connect directly to ground ?? I really appreciate you're help. Thanks Joey

Hi geekinavette, I re-verified those two grounds and here is my dilemma... I disconnected the connector from the map and took the readings from the ecm connector pin as well as from the map ground pin did the same for Coolant Sensor and TPS) and guess what continuity. Now, when I plug the...

Hi Guys, ex-x-fire, as you suggested I checked the Distributor and there is no play. navy2Kcoupe, Did a compression test and the results are the following : 2=165 4=160 6=160 8=160 1=160 3=165 5=165 7=170 any other ideas ?? Thanks

That's allright....

Hi geekinavette, Finally got around to getting under the dash and pull out the two ecm connectors... Verified the white connector pins 12, 13 and 14. Pins 12 and 13 have continuity but pin 14 (map ground) is open. As for the Black connector pins 3, 11 and 15. Pins 3 and 15 have continuity but...

geekinavette, A grounding issue where ?? As per the FSM, measured the MAP voltage with ignition on (engine not running) and the result was 4.9 V... what do u mean it matters a lot ?? As for the CTS, I got no reading from either the harness coming from the ECM or the CTS itself. Since the CTS...

geekinavette, I verified the voltage issue and measured the battery voltage directly its at 12.1 Volts and 14.3 Volts with engine running. As for the MAP I verified its voltage at the harness between terminals a and b its at 4.9Volts. I was also investigating the CTS and found both connector...
