no1parfive Posted January 28, 2013 Share Posted January 28, 2013 While driving, I get short hesitations as if I momentarily loose spark or fuel. I replaced the coil, coil wire, plugs, plug wires, distributor pick-up sensor, and fuel filter, with no success. Will continue to troubleshoot but was wondering if anyone in our club had a similar problem. I'm thinking my next step is to drain the fuel tank due to the possibility that I may have water-contaminated fuel (have already tried the fuel additive that is suppose to eliminate water, but don't trust this procedure). Would appreciate any input from our members regarding this problem. Link to comment Share on other sites More sharing options...
franc944 Posted January 28, 2013 Share Posted January 28, 2013 Try seafoam. Could be carbon. Link to comment Share on other sites More sharing options...
Guest My TC Toy Posted January 29, 2013 Share Posted January 29, 2013 Thats what I would suggest first. Get a good throttle body cleaner and clean as per can instructions drowning the engine at the end. Let the car stand for ten minutes and then restart. It could work wonders.

89TC-16V Posted January 29, 2013 Share Posted January 29, 2013 did you check for codes yet, sometimes the computer picks them up and doesnt kick a check engine light. sounds like failing fuel pump because i had intermittent problems until it finally took a total dump, Link to comment Share on other sites More sharing options...
Guest My TC Toy Posted January 30, 2013 Share Posted January 30, 2013 To check the codes turn the ignition key on-off-on-off and on. Do not start the engine. Then watch the engine light and count the flashes also notice the pauses between flashes. For example one flash pause three flashes translates to code 13. This will continue until all applicable codes have been itemized. Then check the service manuel or here for interpretation.Good luck.\Bob Link to comment Share on other sites More sharing options...
no1parfive Posted March 20, 2013 Author Share Posted March 20, 2013 My problem was caused by a faulty fuel pump, replaced pump, all is now OK. Link to comment Share on other sites More sharing options...
89TC-16V Posted March 21, 2013 Share Posted March 21, 2013 glad your problem was easy. i hope you also replaced the fuel filter and any old brittle hoses from tank to pump and filter to lines Link to comment Share on other sites More sharing options...
no1parfive Posted March 22, 2013 Author Share Posted March 22, 2013 My mechanic did the replacement, he probably only replaced the pump, if I have future problems, I will look at the other items you mentioned. Link to comment Share on other sites More sharing options...

no1parfive Posted March 25, 2013 Author Share Posted March 25, 2013 The filter was replaced by me earlier, don't know if lines were replaced by mechanic, hope he did if they needed replacing, will check lines to verify, thanks for all your help.
